marketization has become an important way to improve the operating efficiency in the power system.In order to ensure the comprehensive benefit of pumped storage power station

this paper studies the centralized bidding model in the pumped storage market.Based on the comparison between the trading mechanisms in Anhui province and Yixing city in Jiangsu province

the shortage of the mode declaring electricity without price is analyzed.Besides

the participants and access conditions of pumped storage market are defined.Considering the encouragement of power plants actively affording the capacity costs

as well as the punishment of collusion and using market force to manipulate the market

the centralized bidding model of pumped storage station is established.Finally
