Abstract:

Objectives Under the current electricity price mechanism, it is difficult for Xinjiang pumped storage power station to fully recover the cost through the arbitrage of peak-valley price difference and participation in electric auxiliary services. Therefore, the capacity and electricity charge dredging mechanism of pumped storage power station is studied. Methods Based on the calculation of the electricity cost of Xinjiang pumped storage capacity, the problems existing in the cost dredging are analyzed. The dredging path of “market-oriented + transmission and distribution electricity price” is proposed for Xinjiang pumped storage power station. That is, the cost is recovered by transmission and distribution price before the maturity of power market construction, and the cost is recovered by marketization after the maturity of power market construction. Results Compared with the pure transmission and distribution electricity price recovery, the “market-oriented + transmission and distribution electricity price” method has higher feasibility in dredging capacity electricity price and the increase of transmission and distribution electricity price decrease by more than 90%, which is a feasible model to calm the excessive rise of transmission and distribution electricity price. Conclusions As a supplementary scheme for the operation cost recovery of pumped storage power stations, the research results will provide a broad market trading space for the pumped storage power stations.
