Abstract: This paper presents a simple controller to enable the inertial response of utility-scale battery energy storage system (BESS). Details of the BESS modeling are presented in this paper. The main contribution of this paper is to demonstrate that inertial controller in BESS help to reduce change to the rate of change of frequency (RoCoF), providing frequency support and improving the system frequency response. The effect of changes in the gain of the synthetic inertial on the system frequency response is investigated using time domain simulations based on DIgSILENT PowerFactory. The time-domain simulations show the advantages of using the inertial controller in BESS to reduce the initial drop in the system frequency. The battery charge control must be improved in order to avoid undesirable battery recharge during critical stages of the frequency response. This is especially dangerous because it can create a second system.
