The importance of Energy Storages System (ESS) without a doubt is started to compete for the importance of Renewable Energy System (RES) nowadays and in the near future. ESS such as grid-scale batteries has the advantage of storing energy and provides many other services and functionalities to the power system. This paper investigates the effect of installing Battery Energy Storage System (BESS) on grid level transmission system to support fast Inertial Frequency Response (IR). Details of the BESS modeling are presented in this paper. The main contribution is to demonstrate that inertial response provided by BESS can create change to the Rate of Change of Frequency (ROCOF), providing frequency support and improving the system frequency response. A simple test system is used to investigate the effect of the inertial controller in BESS to support the system frequency response. Many time domain simulation tests using DIgSILENT PowerFactory are carried out to evaluate the effect of installing BESS with inertial response enabled. The time-domain simulations are conducted to demonstrate the system frequency responses considering: (i) gain of the inertial controller (ii) different sizes of disturbances, (iii) system robustness.
