Frequency regulation considering short-term wind power forecast

Abstract

Wind power forecast is crucial for the design and operation of the power system incorporating large scale of wind power. There have been reports regarding the design of power system considering the wind power forecast, though, very few paper could be found on the operation of power system when wind power forecast are incorporated. In this paper, the performance of the power system incorporating short-term wind power forecast is studied using the field measured data. Energy storage is used to improve the frequency regulation of the system. Due to the power limit of energy storage, variable-structure anti-windup control is applied to ameliorate the performance degradation. Simulation has shown the effectiveness of the controller of the energy storage.
