This article proposes a novel capacity optimization configuration method of battery energy storage system (BESS) considering the rate characteristics in primary frequency regulation to improve the power system frequency regulation capability and performance.
In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
quency regulation services. However, modern power systems with high penetration levels of generation. Therefore, de-loading of renewable energy generations to provide frequency reg- ulation is not technically and economically viable. As such, energy storage systems, which support are the most suitable candidate to address these problems.
