Optimization of Bidding Mode for Capacity Market Considering The Participation of New Energy

One of the construction purposes of the capacity market is to solve the problem of fixed cost recovery of power sources in the pure energy market based on variable cost bidding. With the continuous deepening of the construction of new power systems, more new energy entities will participate in providing capacity resources. If the capacity market lacks consideration for the differences in power cost structure, it will be difficult to meet the different cost recovery demands of various power sources, which will affect the accurate generation of investment incentive signals. This article analyzes the capacity market construction problem under the current differentiated power supply cost structure, proposes a capacity market mechanism design scheme for differentiated power supply cost structure, and verifies it through numerical examples.
