In recent years, amount of renewable energy facilities using wind turbine generator and photovoltaic power system have been increased due to natural environment and resource depletion. Moreover, all electrification apartment houses or residences and electric vehicles have been increased. However, due to the fluctuating power from renewable energy sources and loads, fluctuations of grid frequency and voltage become problematic. This paper presents a methodology of control system frequency and voltage by distributed controllable loads such as heat pump and electric vehicles. By applying power consumption controller using distributed fuzzy control for HP and H ∞ control for battery, fluctuations of grid frequency and voltage are suppressed around a desired value. In order to verify the effectiveness of the proposed system, MATLAB/Simulink is used for computed simulations.
