Secure and economic operation of the modern power system is facing major challenges these days. Grid-connected Energy Storage System (ESS) can provide various ancillary services to electrical networks for its smooth functioning and helps in the evolution of the smart grid. The main limitation of the wide implementation of ESS in the
However, such a SOC regulation method does not consider the effect that ESS setpoint variations may have on system reserves; this factor is taken into account to a certain extent in [47], where

Primary Control. The primary control (or frequency response control) is an automatic function and it is the fastest among the three levels, as its response period is a few seconds. When an imbalance between generation and load occurs, the frequency of the power system changes. For example, with a load increase, the generated power
