it is possible for pumped storage units to participant in spot market or auxiliary service market. Driven by policies such as environmental assessment and clean energy consumption
pumped storage units have space to exert their market power. The problems such as high proportion of intermittent energy fluctuations
equipment failures
large fluctuations in load
and slow climb of large units are analyzed.Thetypicalscenariosandmechanismof the distributed pumpedstorages’market power are clarified. Based on the optimal power flow and probability methods
the market power of the distributed pumpedstoragesystemisquantitativelyevaluated.
