The Evaluating Research Of Economical Benefit Of Pumped Storage Power Station In The Electricity Market

Pumped storage power station can take on the tasks of reducing peak and filling valley, emergency reserve, frequency modulation, phase modulation, etc. in power system. It is of significances for improving the stability and flexibility of electric system, for amending supply quality and raising network safety and economics. It is an economic and effective regulating way to the power system.Traditionally, the research of economical benefit of pumped storage power station emphasizes on the perspective from a technical function, this analysis is simple and convenient, but it isn't clear in the evaluating, and there are often blurred and overlapping. This paper mainly researches the economical benefit of pumped storage power station in the electricity market, so it has a redescription of economical benefit on the basis oftraditional research methods and the view of market, and has a comprehensive evaluation of economical benefit of pumped storage power station with fuzzy analytic hierarchy process, then further analysizes the economical benefit problem of pumped storage power station in the electricity market, so as to support economical policy of pumped storage power station with theoretic reference and strategic foundation.
