Introduction

Corsica Sole, a leading developer in renewable energy solutions, has developed a groundbreaking 50MW/100MWh battery energy storage system (BESS) in Belgium. This project marks a significant milestone as the largest BESS in continental Europe upon its energization. Enersynt was entrusted with the task of ensuring compliance with the Elia Type C grid code requirements for Storage Park Modules (SPMs).

Project background

The Deux-Acren BESS plays a pivotal role in bolstering the stability of frequency within the European electricity network. As renewable energy sources become increasingly prevalent, the intermittency of power generation poses challenges to grid stability. The BESS addresses this by participating in Frequency Control Reserve (FCR) services, crucial for maintaining grid frequency stability. Additionally, it facilitates load shifting, mitigating the fluctuations inherent in renewable energy generation.

Role of Enersynt

Enersynt contributed with expert support throughout the development of the Deux-Acren BESS project, leveraging our extensive expertise in power system engineering to ensure its success. Our contributions encompassed a comprehensive range of tasks and responsibilities, including:

Detailed Electrical Modeling
Our power system engineers created detailed RMS and EMT electrical models of the BESS, seamlessly integrated battery and site controller models into the overall electrical models of the project and capturing its operational dynamics and characteristics. These models served as the foundation for our subsequent analyses and studies.

Grid Compliance Studies
Enersynt conducted exhaustive studies to validate compliance with the Elia Type C SPM connection requirements. This involved assessing various parameters such as frequency stability, voltage control and reactive power capabilities, fault-ride through performance, and small signal stability.

Design Studies
Our team of electrical engineers performed in-depth design studies to determine critical aspects such as short-circuit currents, cable ampacity, and protection coordination. These studies ensured the robustness and reliability of the electrical infrastructure supporting the BESS.

Exhaustive Design Review
Enersynt conducted a thorough design review of the entire electrical grid connection system, identifying potential areas for improvement and ensuring adherence to industry standards and best practices.

Collaboration and Coordination
We collaborated closely with Corsica Sole and other project stakeholders to ensure alignment with project objectives and requirements. Our proactive approach to collaboration facilitated smooth communication and streamlined decision-making processes.

Conclusion

The successful completion of the Deux-Acren BESS project underscores Enersynt's commitment to excellence in power system engineering. By navigating the complexities of grid compliance and design optimization for battery energy storage systems, we have contributed to the realization of this groundbreaking energy storage solution.

The Deux-Acren BESS not only enhances grid stability but also paves the way for greater adoption of renewable energy, aligning with global sustainability goals. Enersynt remains dedicated to driving innovation and advancing the transition towards a cleaner, more resilient energy future.
