Energy storage systems (ESSs) have a quick response and outstanding functions when used for frequency regulation. This paper examines the effect of an ESS used in conjunction with the primary frequency control (PFC) of a power system in South Korea. A simple low order system frequency response (SFR) model is used to undertake a simulation with MATLAB Simulink. The simulation includes gas, hydro and steam turbines and the ESS with the PFC. The results show that the ESS has a remarkable effect in the PFC and that it is more efficient in a weak grid. When more ESSs are added, the substitution effect is weaker according to the simulation results.
