<p>Deliverable D3.7 of the HYPERRIDE project is a demonstration and laboratory testing of a 5 kV DC circuit breaker prototype. This report records the work done in order to achieve this goal.</p>
<p>The requirements on the prototype’s current interruption capabilities are outlined in another task of the HYPERRIDE project and are dependent on the grid to be protected, i.e., the Medium Voltage Direct Current (MVDC) grid of RWTH Aachen. </p>
<p>A circuit breaker based on the Voltage source converter Assisted Resonant Current (VARC) principle has been designed to meet these requirements. The VARC breaking process uses an active current injection method where a Voltage Source Converter (VSC) excites the resonant branch of the circuit breaker to produce a resonant current through the main interrupter of the breaker. The resonant current counters the line current and the net current flowing through the main interrupter momentarily becomes zero. The current to be interrupted is commutated into an energy absorbing branch of the circuit breaker where the magnetic energy stored in the protected line is dissipated. This branch also clamps the voltage across the main interrupter.</p>
<p>This report documents the circuit breaker prototype setup and the relevant current interruption tests. Relevant details (such as largest interrupted current, breaker operation time and fault current suppression time) are also discussed.</p>
<p>It is concluded that a functioning circuit breaker prototype suitable for protecting the Aachen MVDC grid has been designed, built and tested by SCiBreak.</p>

<p>Direct Current (DC) power transmission offers many benefits over Alternating Current (AC) and it is therefore making fast inroads in electrical energy systems all over the world. High voltage direct current transmission High-voltage Direct Current (HVDC) offers efficient transmission over long distances particularly when cables must be used, for instance for subsea links. DC is also used at low voltage, for instance for grids supplying the many servers in data centres. Also at medium voltage (>1500 V – 50 000 V) DC potentially offers significant advantages in many applications. The power conversion chain can be simplified and power flow can be more accurately controlled.</p>
<p>The HYPERRIDE project (HYbrid Provision of Energy based on Reliabilty and Resiliency via Integration of Dc Equipment) contributes to the field implementation of DC and hybrid AC/DC grids. Starting with the definition of most relevant fields of application for DC grids (local microgrids, grid enforcement to overcome congestions, coupling of AC grid sections, etc.), the enabling technologies shall be specified in detail on different levels. One such enabling technology is Direct Current Circuit Breakers (DCCBs) for Medium-Voltage Direct Current (MVDC) grids. Even though MVDC DCCBs are available for DC railway systems e.g., MVDC distribution grid applications have different requirements, mainly with respect to the speed of operation. In recent years different DCCB prototypes for grid applications for MV have been developed using state-of-the-art (mechanical) techniques but also novel solutions, such as the VSC-assisted resonant current (VARC) concept from the project partner SCiBreak AB.</p>
<p>In this report, the most important grid parameters (e.g. grid configuration, converter topology, DC reactor size) impacting the requirements for DC circuit breakers are analysed by means of simplified circuit models. The results of grid simulation studies concerning the consequences of short circuit scenarios for DCCBs in real a MVDC demonstrator grid as well as in a fictional<br>
14 kV grid are also presented.</p>
<p>A list of requirements for MVDC circuit breakers is put together in the report. Moreover, a review of HVDC standards and standards concerning DC railway applications that may be relevant for establishing MVDC standards in the future is given, with the indication of relevant technical brochures and normative documents that are likely to be published in the upcoming years.</p>

<p>Modern distribution grids are transforming due to the increasing amount of load and generation based on DC technologies, whose interconnection is facilitated by the upcoming AC-DC distribution networks. Their fault management is challenged by new issues related to the power transferred among AC and DC sub-networks. In light of this, the present paper proposes a novel Service Restoration (SR) algorithm, specifically tailored for AC-DC distribution grids, that optimizes the re-energization by establishing priorities of disconnected bus groups and computing, as candidate solutions, hierarchical combinations of normally open and normally closed switches. To overcome the limitations of existing approaches, a Multiple Criteria Decision Analysis (MCDA) is proposed to combine and objectively prioritize different SR goals (i.e., the use of telecontrolled switches, the minimization of power losses, and the applicability of the proposed solutions in a defined time horizon), and ultimately make the grid operator benefit from the possibility to flexibly tune different operational objectives. The proposed algorithm allows to effectively discriminating competing solutions, i.e., whence and how to re-energize disconnected buses, and complies with the time requirements for field implementation. The results prove the crucial role of DC sub-networks, associated to the control of power injection from AC-DC converters, in enhancing the SR by improving its targets and increasing the number of re-energized loads. Ultimately, the effect of MCDA comparison parameters on the SR outcomes is quantitatively investigated via global sensitivity analysis, whose adoption is recommended for supporting the grid operator in the algorithm implementation.</p>

<p>Partial operation of the distribution grid in DC instead of AC has been identified as a possible strategy for cost-effective management of future grid scenarios driven by international decarbonisation goals. By applying a simulation tool for techno-economic analysis on synthetic test grid models, it has been shown that the conversion of AC low-voltage grid feeders to DC is a suitable solution to mitigate overloading and decrease voltage fluctuations caused by, inter alia, integration of electric vehicles (EVs), photovoltaic systems (PV) or increased energy demand. Cost models were applied to the simulation results. The economical findings indicate that the implementation of DC in low-voltage grids can be financially beneficial, especially when future developments and learning curves of DC technologies are considered.</p>

<p>At the RWTH-Aachen University a new Campus West will be built. This Campus area includes a thermal network as well as an IT-center, PV power plants and charging stations for electric vehicles. It is considered to connect these components using a customer owned medium voltage grid, in order to maximise self consumption. Within this deliverable, a study is implemented based on the plans for Campus West, which identifies the advantages of using a Medium Voltage Direct Current (MVDC) grid configuration compared to a 10 kV Alternating Current (AC) reference grid for that purpose. Parameters considered in this analysis are different voltage levels, transformer efficiency, converter efficiency and cable transmission losses. The aim of this study is to identify the key influencing factors along with the conditions that result in the MVDC grid configuration being more feasible than the AC reference scenario.</p>
<p>In order to carry out the comparison between AC and Direct Current (DC) systems, grid systems are first designed accordingly for the use of the respective technology. Within the scope of the comparison, both monopolar and bipolar DC system configurations are compared with the AC reference scenario.</p>
<p>For the three-level neutral-point-clamped converter (3LNPC) and the modular three-phase dualactive bridge (DAB3) the efficiency curves are calculated by means of simulation.</p>
<p>In order to compare the efficiency of the concepts, the power flows for a whole year are calculated in hourly resolution based on the load profiles, including the resulting losses in the converters, transformers and cables. The results show the following:</p>
<ol>
<li>DC power transmission is advantageous for voltage levels UDC >= 5 kV compared to the 10 kV AC reference scenario.</li>
<li>Considering material consumption as well as efficiency allows to identify monopolar grid structures as more advantageous, since they only need two conductors instead of three.</li>
<li>While designing the DC-DC converter, it is financially rewarding to oversize the converters instead of sizing them only for the maximum power needed, if the load profile is constant. Hence, a more efficient operating point can be achieved.</li>
<li>If the efficiency of the MVDC-LVDC converter is 1.7 % higher than the efficiency of the active rectifier used in the AC reference scenario, the implementation of a MVDC grid is potentially more feasible.</li>
<li>The losses in the MVDC-MVAC substations exceed the losses in the MVAC-MVAC substation by far, because of the additional converter needed for rectification in the DC scenarios.</li>
<li>Distributing the power supply evenly among the active substations using power-flow control does not make the substations more efficient, even though it allows to design the components for smaller nominal power values. However, distributing the power supply leads in this example to higher cable transmission losses.</li>
<li>Increasing the cable transmission distances by a factor of ten leads to the DC systems being more efficient than the AC-reference system. Especially for monopolar configurations with grid voltages UDC >= 12 kV.</li>
</ol>
<p>Limitations and critical review of this analysis:</p>
<ol>
<li>As the case study includes a consumer that withdraws constantly a high amount of power, it could be that the application of the results to other use cases needs to be critically evaluated, especially concerning the derivation of more generalised conclusions.</li>
<li>The comparison of the cable transmission losses is based on the assumption that the current densities that can be realised without exceeding the thermal limits of the cable are the same for AC and DC transmission.</li>
</ol>
<p>In the context of this case study different parameters have been identified, that lead to better feasibility of a DC-grid, compared to the AC reference grid scenario. While the impact of the cable transmission losses is comparably low and only becomes relevant when the transmission length is increased, the key influencing factor is the efficiency of the converters used in the grid systems. DC grid scenarios become potentially feasible after nine years or more, if the DC-DC converters connecting the MVDC grid to the LVDC grids have a maximum efficiency that exceeds the efficiency of the active rectifiers in the AC reference scenario by 1.7 %. Also, for the use case investigated in this case study, the efficiency of the MV Active Front End (AFE) was identified to have significant impact on the overall system efficiency.</p>
<p>Future work should further investigate the modelling of converter efficiency, in order to obtain results that can further differentiate between different types of semiconductor switches or types of converter control. In addition, further consideration should be given to the aspect of material consumption by determining tolerable current densities in DC cable configurations and comparing the material consumption of the medium frequency transformers and 50 Hz transformers implemented in different DC and AC grid configurations.</p>

<p>The Component Sizing Tool is an online tool, which can be used for the sizing of system compo-nents used within Alternating Current (AC), Direct Current (DC) and hybrid Alternating Current and Direct Current (ACDC) networks. The Deliverable of the Component sizing Tool is an online Component Sizing Tool, with an additional report explaining the calculations and simulations in the background. The simulation model and the online tool, however, remain the intellectual property of Austrian Institute of Technology (AIT), the code itself will not be made public. The component sizing tool for technical and economic optimization within the HYPERRIDE project is lead by AIT who is responsible for the tool development and implementation, in collaboration with additional partners EMOTION and ASM, whos role are to provide the neccessary profile data for the simulations.</p>
<p>The component sizing tool for economic optimisation will provide a technical and economic base for finding the optimal component size solution for three different use cases within the HYPERRIDE project. The first use case is as an addition to the Grid Planning Tool for the development of Hybrid ACDC microgrids, for the simplified simulation of battery storages within Hybrid ACDC micro grids. Secondly, the tool will be used for simulations in the Italian pilot as EMOTION and ASM are the main contributors. Therefore, input data from the partners will be pre-implemented into the online tool to simplify the tool usage. As a third use case, the tool will be used to generate input parameters for creating business models, regulatory assessment and identify consumers.</p>
<p>The online Component Sizing Tool is currently available under <a href="http://sizing-tool.hyperride.eu">http://sizing-tool.hyperride.eu</a> (Username: HYPERRIDE, password: Component-sizing-Tool).</p>

<p>For the implementation of the DC microgrid part of the Italian demonstration in particular a Low Voltage Alternating Current (LVAC) to Direct Current (DC) Active Front End (AFE) is required. Therefore, within HYPERRIDE a bidirectional 34.5 kVA Alternating Current and Direct Current (ACDC) power electronics converter unit from AIT has been used as a basis to implement control algorithms to serve as an AFE and to supply DC microgrids from LVAC power lines. The bidirectional topology enables further to provide power flow towards the DC grid as well as to remove excess generation when a surplus of energy is available.</p>
<p>The developed droop control uses the voltage of the Point of Common Coupling (PCC) as a parameter to control the delivered power. Within the respective task, the control algorithm has been defined, tested and validated in a Controller Hardware-in-the-loop (C-HIL) environment.</p>
<p>In a subsequent step, the unit has been set up as real hardware to test the control algorithm. Successful tests were carried out in the AIT laboratory premises and results are reported in this document.</p>

<p>This report summarises the reasons of the necessity of performing arc fault tests and arc fault calculations for new hybrid AC&DC-grid concepts which are targeted in HYPERRIDE. It gives an overview about the normative references and describes the workflow of doing arc fault calculations and how to validate them with arc fault experiments. It describes the starting point for the physical model building which is necessary for both, the room average method and the Finite Element Method (FEM). The FEM-method use Computational Fluid Dynamics (CFD)and solves the Navier Stokes equations. First experimental results and a FEM calculation are discussed. A new enclosure is presented, which will be used in task T3.4 for performing systematic AC&DC arc fault experiments. The complicated physics of arcing requires a strong interaction of theory and experiments. Therefore a work flow for doing arc fault simulations in combination with arc fault experiments has been worked out.</p>

<p>The role of distributed energy resources is increasing significantly in electrical power systems due to many environmental, economical, and political drivers. This transition has also put the electrical distribution grid in a central role. The challenges arising from this transition are largely being addressed under Smart Grid (SG) initiatives. Although there is no standard definition, in general, a smart grid refers to a method of incorporating intelligence into the operation of distribution grids to increase flexibility and performance. For electrical power systems, Alternating Current (AC) distribution grids are a well-known infrastructure that has been in use for a long time. This infrastructure can be assisted by Direct Current (DC) technologies as a possible backbone to increase, for example, Renewable Energy Sources (RES) hosting capability; however, they must be designed on a solid basis to allow for rapid roll-out and integration. It is critical to provide and test suitable methodologies and resources to lower entry barriers for early adoption processes to maximise the implementation capability of new DC technologies.</p>
<p>The HYPERRIDE project aims to support this transition toward the transformation in the electrical grid infrastructure by laying the groundwork for widespread adoption of DC technology. The future distribution grid both at the Low Voltage Direct Current (LVDC) component to Medium Voltage Direct Current (MVDC) backbone is planned to be demonstrated at three pilot sites(Germany, Italy, and Switzerland) implementing relevant use cases. These pilots will provide valuable insights as well as help in identifying the gaps in knowledge and possible solutions for the various focus areas. The use cases to be used for the implementation are documented in this deliverable along with the standards and background, the methodology and the analysis.</p>
<p>To perform a systematic analysis to discover the use cases that would be interesting to implement and cover the goals of the project, a well-thought-over methodology is needed. This methodology should be based on the well-known standard and reference architectures to make the communication and dissemination among the consortium and beyond be made easy and effective. A methodology is derived based on National Institute of Standards and Technology (NIST) and SGAM to identify first the context and boundaries and defining the use cases.</p>
<p>With the help of partners, several workshops are conducted to collect the inputs. These inputs provided the basis for the analysis that later resulted in the form of the summary use cases. These summary use cases are then debated in the workshops and, based on the aim of the pilot, are adopted for the development of the detailed use uses. The detailed use cases are then documented using International Electrotechnical Commission (IEC) "Use Case Methodology" method using IEC 62559-2 templates. The background, methodology and analysis, and the summary use cases are described in detail in this report while the adopted and detailed use cases for individual pilot sites implementations are included in the three appendices of the document.</p>

<p>In modern distribution grids, the access to the growing amount of data from various sources, the execution of complex algorithms on-demand, and the control of sparse actuators require on-demand scalability to support fluctuating workloads. Cloud computing technologies represent a viable solution for these requirements. To ensure that data can be exchanged and shared efficiently, as well as the full achievement of the cloud computing benefits to support the advanced analytic and mining required in smart grids, applications can be empowered with semantic information integration. This article adopts the semantic web into a cloud-based platform to analyze power distribution grids data and apply a service restoration application to re-energize loads after an electrical fault. The exemplary implementation of the demo is powered by FIWARE, which is based on open-source and customizable building blocks for future internet applications and services, and the SARGON ontology for the energy domain. The tests are deployed by integrating the semantic information, based on the IEC 61850 data model, in the cloud-based service restoration application and interfacing the field devices of the distribution grids. The platform performances, measured as network latency and computation time, ensure the feasibility of the proposed solution, constituting a reference for the next deployments of smart energy platforms.</p>

<p>Analysing and predicting system performance and availability depends largely upon reliability and maintenance data. Attaining statistically credible data can require observations from several years of operations. Fortunately, this data collection process can be quickened if this data is shared within the community of organisations in the same working domain.</p>
<p>The goal of this task is to develop an open reliability information system to provide a common platform for storing and sharing reliability information on components in the area of energy management. The work is accompanied by a prototyping activity that shall prove the concept and create a foundation for gathering reliability information about selected key systems. A special care is taken to ensure technical efficiency and meeting the legal and administrative constraints emerging from cooperation with industrial partners and regulatory bodies.</p>
<p>The open reliability information systems focuses on industrial infrastructures in large scale facilities. The shared data will consist of system and subsystem reliability and maintenance statistics, information on system structure and operation conditions as well as estimation on data quality. The data will be used in quantitative reliability and availability assessments. The stored data and intended use differ from traditional maintenance databases that are used for storing individual equipment failure events.</p>
<p>The development of an open reliability database started in the context of the Future Circular Collider - Cern (FCC) research project, where a platform for sharing reliability information played a big role in the area of accelerator technology and this community did not have a platform yet. However, successful examples of this concept exist in oil, nuclear and wind power industries and this existing knowledge shall be used to benefit this project. This knowledge includes OREDA, EIReDA, SPARTA and WInD-Pool projects and ISO 6527, ISO 14224 and ISO/TR 12489 standards.</p>

<p>Resilient hybrid Alternating Current (AC)-Direct Current (DC) power grids are discussed as a potential future solution for distribution power grid flexibilization to enable connecting a high-share of renewable sources (photovoltaic, wind), new DC-based loads (electric vehicles, heat-humps), and storages instead of cost and carbon emissions-intensive AC standard grid solutions (new cables and power transformers) for grid reinforcement when existing grid parts come to their capacity and power quality limits and also for new installations. This work identifies main drivers and technology requirements, important use-cases, standardization, regulatory, and market needs. It introduces as examples the actual running European demonstration projects HYPERRIDE and TIGON funded by the European Commission and highlights their common positioning and future activities/developments on the topic of hybrid AC-DC power grids based on their description of work and the findings of other international DC-grid initiatives like actual published CIRED WG-2019-1 “DC distribution networks” report and CIRED 2021 Round Table “DC networks” results which are also summarized.</p>

<p>ICT plays a crucial role in a smart grid: Digital technology allows to monitor and manage the transport of electricity from all generation sources to meet the different electricity demands of end users. A central logic allows to coordinate the needs and capacities of all generators, network operators, end users and stakeholders in the electricity market in order to:</p>
<ul>
<li>optimise the use and operation of resources;</li>
<li>minimise costs and environmental impacts;</li>
<li>maximise the reliability, stability, and resilience of the network.</li>
</ul>
<p>Another potential approach for the sensing and control of power distribution systems could be a decentralised logic. From the ICT perspective, decentralised logic’s are interesting in view of their better scalability and better control on privacy.</p>
<p>Measurement sensors, actuators, automation devices, information technology and communication equipment permit to exchange information and to send command, control, and automation signals from the digital management system, which represent the intelligence of the network, to the physical equipment of the infrastructure electric. The control and actuation signals sent<br>
to the physical devices of the network are no longer responding to the centralised and unidirectional logic of traditional systems only, but they are the result of advanced management logic’s that are managing the flows of energy and power in real time, determining the values of “optimal” setups for distributed generation and load resources (Valenti & Graditi, 2020).</p>
<p>The HYPERRIDE project aims to design and implement an Open ICT Platform enabling:</p>
<ul>
<li>the seamless integration and management of devices, regardless of how smart they are;</li>
<li>scalable and interoperable collection and management of data that support near real time observability and optimisation of the operation of modular and resilient hybrid Alternating Current (AC)/ Direct Current (DC) grids;</li>
<li>the transmission of commands/setpoints for the safe and reliable operation of the grid;</li>
<li>detection, prediction, prevention of technical and cyber-contingencies.</li>
</ul>
<p>This document reports the results of the activities conducted in HYPERRIDE aiming at the elicitation and analysis of functional and non-functional requirements of the Open ICT Platform and high-level design of the platform architecture in terms of static and dynamic behaviour of the system.This document is based on the outcomes of Deliverable D2.2 “Use case description, specification and implementation roadmap report”. Moreover, a questionnaire including general and customised questions has been submitted to Work Package (WP) leaders and to pilot leaders to collect expectations from the Open ICT platform in terms of functionalities, standards, data model, constraints, special technologies/tools needed, data necessary for the business processes.</p>
<p>A high-level description is given for each logical module that make up the architecture. Main information exchanges between architectural modules are described. Review and retrospective activities will be conducted to reflect on the iterations of requirements engineering reported in this document in the attempt to improve the process going forward and taking into account the<br>
needs that will emerge in the other WPs. New and refined requirements that will emerge in the next phases of the project will be reported in the accompanying report of Deliverable D5.6. Low level details on architectural components and their interdependencies, on processes, and instructions for the deployment and use will be provided in the accompanying report of Deliverables D5.6 and D5.8. Furthermore, the document gives a short description of the energy services that will be evolved in HYPERRIDE according to the needs of hybrid AC/DC grids.</p>
<p>This document will be used as a starting point for the integration activities foreseen in later on in the project that are summarised in Deliverable D5.6 Open HYPERRIDE ICT platform (preliminary version) and following D5.8 Open HYPERRIDE ICT platform (final version).</p>

<p>Over the years, the distribution grid has changed considerably. Today, the great production of energy by Renewable Energy Sources that produce fluctuating power into the distribution grid requires a greater ability to manage the low voltage section of the grid, since energy producers and users are more and more connected to the low voltage grid. Today the role of the power grid customer, whether producer, user, or prosumer, is central in the sustainable and reliable management of a modern distribution grid.</p>
<p>The HYPERRIDE project in the Italian pilot develops a hybrid Alternate Current(AC)/Direct Current (DC) distribution grid that matches the needs of AC and DC users/prosumers with the needs of Distribution System Operator (DSO) to limit congestions at the nodes of the grid and promote the local consumption of the energy self-produced. The achievement of this synergy is based on flexibility criteria provided by the grid customers. Flexibility in consumption and production by the customers increases the sustainability and resilience of the grid as a whole, with impact mainly on Low Voltage (LV) grid but with benefits also on Medium Voltage (MV) grid at an upper level of hierarchy in the power grid. The effect of local variations in the hybrid AC/DC grid will be related to the effects on the entire grid, including the MV section.</p>
<p>The selection of DC/DC and AC/DC converters, hybrid grid architecture, protections, monitoring and control systems is based on reliability and multi-operability requirements of all the systems involved. The pilot performance evaluation will be related to the fixed objectives in order to detect the deviations from the expected results and if necessary implement corrective actions and different settings in the equipment operating thresholds. The modern conventional grid is by nature a dynamic and adaptive system, the hybrid grid is even more so. The adaptive behaviour of the AC/DC hybrid distribution grid is in compliance with the requirements of the existing real AC distribution grid to improve the reliability of the whole system and therefore supply better services to the grid customers. The pilot set-up and test specification sets the Use Cases requirements to achieve and evaluate the synergy between all systems involved in the project.The impact of the new DC grid will be also evaluated in the real distribution grid operation.</p>
<p>The definition of the pilot setup and test specifications is the result of a close collaboration with Work Package (WP) 2 and the identification of three use cases to test the integration requirements and validate them in a real distribution grid where coexist electric vehicle charging systems, Photovoltaic (PV) power plants, storage systems, critical loads and a DC system control infrastructure dedicated to the pilot. In addition, all required additional equipment including sensors, AC controllers, Application Programming Interface (API) and other hardware modules implemented or existing in the pilot will be tested.</p>

<p>With the increasing penetration of DC based devices and the improving performance of power electronics converters, more and more advantages foster the deployment of hybrid AC-DC distribution grids. Although the operating control of AC-DC grids is consistently studied in the literature, several protection aspects need further analysis. This paper focuses on the reliability of AC-DC distribution grids, proposing a Service Restoration (SR) algorithm to efficiently re-energize the disconnected nodes in case of electrical faults. To determine the SR solution, the algorithm inspects multiple criteria together: the number of reconnected nodes, the minimization of power losses, the presence of telecontrolled switches, the criticality of the nodes facilities and the restoration feasibility according to power forecasts. The evaluation of reconfiguration topologies is based on the operational limits of AC-DC converters and energy sources; additionally, the power transfer is controlled by setting as optimization objective the losses minimization. The conducted tests, considering different load and generation configurations, prove the applicability of the proposed algorithm in evaluating the feasibility of reconfiguration topologies and computing the near-optimal SR solution.</p>

<p>The operation of a hybrid Alternating Current - Direct Current (AC/DC) grid relies on power electronic converters interfacing different sections of the grid. Each converter controls primarily voltage, current or transferred power. Together they achieve stable operation of the grid. Within this Work Package (WP) a layer based control approach for the converters in a hybrid grid has<br>
been proposed. As a reference system the HYPERRIDE demo site in Aachen was considered since the developed control algorithms are to be implemented there. Furthermore, it is important that the system can be operated under no communication, with the converter level control alone.</p>
<p>With these specifications in mind, control algorithms for different converter topologies were developed and implemented on hardware test setups.The existing GE 3L-NPC DAB and downscaled 3L-NPC AFE testbenches at the demo site in Aachen, together with the for their operation already developed converter control algorithms, served as basis for the contributions of this deliverable. Those contributions include:</p>
<ul>
<li>Dead-time compensation of Dual Active Bridge (DAB);</li>
<li>Active thermal balancing of DAB;</li>
<li>Hardware implementation and verification of Three Level Neutral Point Clamped (3L-NPC)</li>
<li>DAB modulation;</li>
<li>Hardware implementation and verification of Instantaneous Current Control (ICC) of DAB;</li>
<li>Hardware implementation and verification of 3L-NPC Active Front End (AFE) control;</li>
<li>Down-scaled two-level DAB testbench.</li>
</ul>
<p>The DAB topology is addressed because it couples Direct Current (DC) parts of the system and provides galvanic isolation. Moreover, it can reach high efficiencies with the proposed control algorithms. Basic operation characteristics of the DAB are covered with Single Phase-Shift (SPS)<br>
mode. Different modes of operation are presented to allow interfacing of energy storage systems and other types of loads and sources to the grid while maintaining soft-switching operation. A dead-time compensation is proposed to mitigate the effects of dead-times on operation of the DAB. In order to balance the thermal stress on the devices of the DAB, a balancing<br>
strategy is implemented. The control algorithms were tested and verified on a down-scaled hardware setup. An advanced three level modulation scheme and ICC for dynamic operation of the DAB were implemented and tested on the full-scale GE 3L-NPC DAB converter which is part of the demo site.</p>
<p>The coupling of Alternating Current (AC) and DC parts of the grid is achieved with AFE converters. The required control algorithms for current, voltage and power control are reviewed. They were implemented on a down-scaled 3L-NPC converter. Additionally, the balancing control of the split DC link of the 3L-NPC was experimentally verified.</p>
<p>An overview of the different proposed control layers is given. The features of each layer are discussed. Simulations were conducted to verify overall system stability under operation with converter level control since the HYPERRIDE demo site is currently under commissioning.</p>

<p>This report provides insight in the planned enabling solutions to be developed within HYPERRIDE project. The infrastructure requirements, demonstration site descriptions and definition of Key Performance Indicators (KPI) outlined here have to be read in context with the connected deliverables D2.2 and D2.3.</p>
<p>Based on the availability of Direct Current (DC) based renewable energy resources and power electronics converters it is a possible development to evolve from currently used Alternating Current (AC) technologies to DC grid systems. Some of the benefits are:</p>
<ul>
<li>improved grid resiliency</li>
<li>decreased cost and increased energy efficiency on system level</li>
<li>facilitated integration of renewable energy sources and DC based loads</li>
<li>increased transmission capacity</li>
<li>reduced voltage fluctuations</li>
<li>reduced control and synchronisation effort</li>
<li>environmental benefits</li>
</ul>
<p>Throughout the last decade, DC systems have been demonstrated for various use cases and rising number of pilot installations all over the world. In the report a description of the most no table installations can be found. A majority of theses demonstrators have been established in Asia. With the analysis of these instalments was possible to identify potential gaps for new infrastructures from interoperability demands in Information and Communications Technology (ICT) solutions, means of failure mitigation and prevention, mechanisms of safety such as breakers etc. The solutions in HYPERRIDE as described in D2.3 will be demonstrated in the pilot sites in Germany, Switzerland and Italy as described in the report.</p>
<p>To provide a toolbox for the analysis of the individual infrastructures a set of KPIs have been defined based on the methodology to evolve from available AC definitions proven to be beneficial and adapt those, if applicable, to DC grid infrastructures. In case a gap has been identified new definitions are proposed.</p>
