Analysis on the uncertainty factors of pumped storage power station construction investment under the Chinese characteristic power market environment

Abstract

Abstract Pumped storage power stations provide security and support for the new power system with new energy as the main body. Pumped storage power stations are encouraged to participate in the spot electricity market and form electricity price in a competitive way. Based on the identification of the uncertain factors and the calculation of price fluctuation of the pumped storage power station participating in the electric power spot market with Chinese characteristics in the electric power market environment, this paper adopts the sensitivity analysis method to analyze the impact of the change rate of the price spread on the internal rate of return on capital of the pumped storage power station in the trading day, and draws the following conclusions according to the calculation examples:When the sensitivity coefficient is positive, the extraction spread is greater than the benchmark extraction spread by 25%, and with the increase of the extraction spread, the internal rate of return is greater.
