Abstract

Recently, much attention has been paid to the integration of renewable energy into power system. However, it is concerned that the frequency fluctuation is caused by a large integration of the renewable energy. Therefore, we focused on the fast demand response system to suppress the frequency fluctuation. Controllable loads on demand side such as heat-pump-based water heater or batteries of electric vehicles (EV) are operated at a high speed in the fast demand response (Fast-DR) system to suppress the frequency fluctuation. A power system is modeled with communication delay when sending control signals from a control center to the controllable equipment on the demand side. Effectiveness of the Fast-DR was verified through digital simulation on the power system model in this research.
