Battery energy storage systems can play a key role in future renewable energy systems—but how they are operated is crucial for both profitability and battery life, according to research by Meryem Ahouad at Chalmers University of Technology.
Battery energy storage systems can play a key role in stabilizing the electricity grid, but the way they are operated has a significant impact on both battery degradation and profitability. This is the conclusion of new research from Chalmers University of Technology.
In her licentiate thesis, Meryem Ahouad, a doctoral researcher at the Division of Electric Power Engineering, investigated how large-scale battery energy storage systems perform when providing Frequency Containment Reserve (FCR) services in the Nordic power system.
By combining advanced simulation models with experimental aging data, she evaluated both battery degradation and economic performance under realistic operating conditions.
