Based on the pumped storage electricity price mechanism and conforming to the construction law of China's spot power market, this paper established a life cycle benefit evaluation model of pumped storage plant through different market stages, and the evaluation results can provide decision-making reference for investors and national policy makers.
The full capacity of the pumped storage plant can freely participate in the spot market and auxiliary service market. At the same time, pumped storage plants can also obtain capacity income from reliability capacity market and regulatory capacity market. 4. Economic benefit model
As an independent market subject, the participation of the pumped storage plant in power trading increases its economic benefits. The results verify the effectiveness of the phased price mechanism and economic accounting model designed in this paper.
When the market mechanism is not perfect, gradually reducing the proportion of the approved capacity price covering the capacity of pumped storage plants will improve the economic benefits of pumped storage plant and help the pumped storage plant to smoothly convert to the status of an independent market subject. 1. Introduction
According to the division of market mechanism and the design of market connection mechanism, the revenue of the pumped storage plant in the initial stage of the market comes from electricity revenue, capacity electricity revenue and “two rules” compensation.
Analyzes price mechanism's effect on the development of pumped storage plant. Put forward the price market connection mechanism on pumped storage plant. A life-cycle economic benefit model undergoing multi marketization stages is proposed. The policy impact is evaluated by simulating the approval process of capacity price.
