Model Validation of Sector-coupled Energy Systems– Heat & E-Mobility Use Cases (MOVES)

 The project "Model Validation of Sector-coupled Energy Systems– Heat & E-Mobility Use Cases"(MOVES) addresses the need for validating emerging technologies within sector-coupled energy systems to facilitate their integration into the broader energy landscape. This project specifically focuses on Electric Heat Pumps (EHPs) and Battery Electric Vehicles (BEVs), which are pivotal components in achieving sustainable energy goals. By leveraging advanced modeling techniques and the state-of-the-art facilities available at Technical University of Denmark(DTU) Energy System Integration Lab (SYSLAB), MOVES aims to bridge the gap between theoretical models and practical, real-world applications.

The contemporary energy sector demands innovative solutions to balance efficiency, sustainability, and reliability. Technologies such as EHP and BEV play a significant due to their potential for increasing energy efficiency and reducing carbon footprints. However, the analysis of the behavior of these components integrated in the energy system requires validation methodologies to ensure accuracy and reliability in various operational scenarios.

Dynamic simulation is an effective tool for analyzing energy systems. The Hamburg University of Technology (TUHH) is therefore developing the TransiEnt-Library, a modeling library based on the free description language Modelica, as part of various research projects and making it available as open-source. Some components of the current and future energy system are already integrated into this library. The aim of the MOVES project is to extend and validate components of the TransiEnt library in lower energy systems, i.e. primarily EHPs and BEVs, with regard to model depth and accuracy.

As part of the MOVES project, the SYSLAB laboratory infrastructure was used to carry out various measurement campaigns from which the functionality of the components can be derived. The measurement campaigns for the EHPs and BEVs were divided into stationary and dynamic measurements. While the stationary measurements essentially depict the efficiency of the components, the dynamic measurements focus on the behavior of the components during operating point shifts.
