This work presents a control strategy for the reduction of the impact of intermittent renewable sources, such as solar and wind power, in the frequency regulation of Kitami's power system, by using sodium-sulfur (NAS) batteries and a Model Predictive Control (MPC)-based control system. First, the effects of the introduction is evaluated considering the current load frequency control (LFC) capabilities and limits of Hokkaido's power system. Secondly, the proposed controller is applied to the NAS battery and high-penetration scenarios of wind and solar power are considered. Results show that the controller keeps satisfactorily the system's frequency inside permitted ranges.
