A Proposal of Fair Output Curtailment Method for Photovoltaic Generators and Wind Farms

In an electric power system featuring an abundance of renewable energy sources (RES), such as photovoltaic generators (PVs) and wind farms (WFs), the need for curtailing RES output arises to maintain supply-demand balance during periods of anticipated excess generation across the electric power system. Ensuring equitable treatment among RES units regarding curtailment and minimizing overall curtailed energy become pivotal. This paper introduces a method to equitably establish upper output limits for each RES. The effectiveness of these methods is substantiated through numerical simulations. It was found that the key to achieving fairness is to uniformly improve the output control performance of RESs.
