This shift has elevated energy storage systems (ESSs) from supportive infrastructure to a central pillar in grid frequency regulation—a role previously dominated by conventional rotating machinery. Frequency Instability: A Consequence of High Renewable Penetration As synchronous generators give way. .
However, due to its strong output volatility and diculty in scheduling, it has brought unprecedented challenges to the frequency stability (Sun et al. 2019). e traditional frequency control mechanism based on inertial response is no longer fully adaptable to the regulatory needs of new energy power.
