Study On Pricing Of Pumped-storage Plant Based On Ancillary Services Market

In the traditional electric power system operation, little attention has been put on the problem of the compensation of the pumped-storage plant's dynamic benefits. But in the environment of an electric market, it must be solved by reasonable price policy. The key is to change its various dynamic benefits into economic benefits. At present, the attention for the ancillary services pricing in the electric power system brings the opportunity for the solution of the problem.Under the framework of the ancillary services pricing, this dissertation analyzes the value compensating mechanism of the pumped-storage plant. Based on that, under the ancillary services market environment, this paper analyzes the cost of pumped-storage plant's auxiliary service, and set up a model of functional pricing based on the ancillary services, then study on the sensitivity analysis of functional pricing pumped-storage plant's auxiliary service. At the end of this paper, as a part of the value compensating mechanism on the pricing of the pumped-storage plant, analyses the on-grid price and market competitive power based on peak-valley and time sharing price of Hohhot pumped-storage plant.
