Pumped storage power stations play a positive role in peak load regulation

new energy consumption and the realization of the“double carbon”goal. In order to study the cost diversion of pumped storage power stations in the process of power market

firstly the historical evolution of the provisions of national policies on the price mechanism of pumped storage power stations are combed systematically

and the cost recovery methods of foreign pumped storage power stations are investigated. On the premise of understanding the existing policies and practices

combined with the construction process of China’s power market

it is divided into three stages：the initial stage

the transition stage

and the mature stage. According to the construction situation of each market in different stages

the price mechanism of pumped storage power stations in different market stages is clearly given

and the analytical mathematical model of electricity price is established to effectively guide the costs incurred by pumped storage power stations. Considering economic development

price level

affordability and other factors

three principles for cost diversion of pumped storage power stations are determined

and six single and combined modes of cost allocation are proposed

which has certain theoretical and practical significance for the development of pumped storage power stations in China.
