Is dynamic energy storage a control strategy for adaptive secondary frequency regulation?
Abstract: An innovative control strategy for adaptive secondary frequency regulation utilizing dynamic energy storage based on primary frequency response is proposed.
Can hybrid energy storage systems be integrated into secondary frequency regulation?
Particular emphasis is placed on incorporating hybrid energy storage systems (HESS) into secondary frequency regulation. The objective function for the intraday process, represented by Eq.

Why is disengagement from secondary frequency regulation important?
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.
Can secondary frequency regulation improve microgrid resilience?
