How can pumped storage plant become an independent market subject?

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

Should pumped storage plants be evaluated?

The benefit evaluation of pumped storage plants should be developed according to the change of its functional role in power system.

Does price mechanism affect the development of pumped storage plant?

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.

How pumped storage plant can benefit from economic benefit model?

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
