Offshore Wind Power Plant Stability and Resiliency: Integrating Cross-Domain Insights

The offshore wind energy sector presents significant opportunities for advancing global
renewable energy targets. As the urgency to achieve sustainability goals intensifies, the expansion
of cost-effective, low-carbon technologies becomes paramount. Offshore wind, a rapidly maturing
technology, has the potential to transform future energy systems. According to the International Energy
Agency (IEA), offshore wind capacity is projected to increase fifteen-fold by 2040, establishing it as a
cornerstone of global decarbonization efforts.

From a technical standpoint, integrating wind energy into the grid and maintaining power
system stability are critical challenges. Ensuring power stability in wind power plants (WPPs) necessitates
the deployment of advanced technologies and methodologies for comprehensive monitoring,
analysis, and control. Power stability encompasses a system’s capacity to sustain consistent voltage,
frequency, and operational equilibrium amid disturbances.

Within the EU H2020 InnoCyPES project, an interdisciplinary approach has been adopted to
deploy digital tools that enhance offshore WPP stability. The objective is to equip grid operators
and WPP managers with tools for monitoring and controlling power stability, improving communication
infrastructure resilience, reducing testing and deployment costs, and ultimately evaluating the value
these tools add to WPP operations.

A systems perspective reveals the main challenges facing offshore WPPs. Firstly, grid integration
requires advanced technologies to ensure stability and efficiency. Secondly, the cyber layer
demands robust cybersecurity measures and a resilient communication infrastructure to safeguard
against potential threats. Lastly, societal factors are crucial; public acceptance and support from policymakers
are essential for the successful deployment of wind energy solutions, significantly impacting
both financial backing and regulatory frameworks.

In response to these challenges, relevant research has been conducted across various layers.
Solutions for grid integration include power quality monitoring, short-circuit current estimation from
inverter-based resources, transient stability assessment, and validation of electromagnetic transient
(EMT) models throughout the lifecycle of wind turbines and WPPs. Additionally, next-generation
supervisory control and data acquisition (SCADA-NG) systems utilize a software-defined communication
network architecture to enhance data resilience and implement advanced intrusion detection methods
for cyber threat mitigation. The introduction of dynamic cost-benefit analysis (CBA) captures the
evolving impacts of digital technology adoption, offering valuable insights for informed decision-making.
A proposed framework for integrating cyber-physical solutions emphasizes coherence and
interoperability. This adaptable approach ensures that the use cases and solutions discussed can
enable synergies, offering a unified methodology for managing complex WPPs. It aligns closely with the
InnoCyPES project’s goal of establishing an integrated platform to govern the lifecycle of cyber-physical
WPPs. The primary aim is to integrate use cases in a manner that promotes contextual relevance and
interoperability.

This framework lays the groundwork for future platforms focused on managing the planning
and operation of WPPs The target audience includes transmission system operators (TSOs), WPP
developers, original equipment manufacturers (OEMs), end users, regulatory authorities, academia,
industry stakeholders, and interdisciplinary researchers.
