1. Introduction Secondary frequency control (SFC), also named as automatic generation control, corrects the area control error from primary frequency control, and brings the frequency back to the nominal value . As with the fast response time, battery energy storage system can provide better signal tracking in SFC.
Disengagement from the secondary frequency regulation not only accelerates the restoration of grid frequency but also ensures precise and error-free adjustment of the system frequency, thereby improving tracking and dynamic performance. The effectiveness of the proposed control strategy is demonstrated through simulation.
At the same time, with the rapid development of renewable energy and the increasing demand for flexibility in power systems, electrochemical energy storage technology has shown great potential in frequency regulation due to its unique advantages.
