现货市场环境下的可再生能源消纳责任权重市场机制设计

Market Mechanism Design of Renewable Energy Accommodation Responsibility Weight under Spot Market Environment

可再生能源消纳责任权重制度与电力现货市场建设在同步推进。为协调常规电力交易品种与消纳责任权重交易品种之间的关系,实现消纳权重制度顺利执行,设计了现货市场环境下的可再生能源消纳权重市场机制。分析了现货市场背景下消纳权重制度实施的难点,从市场主体、交易品种、交易方式与周期、交易流程4个方面设计相关市场机制,创新性提出包含电网主体的超额消纳量市场设计,并通过算例分析论证包含电网主体的超额消纳量市场对促进新能源发展的积极意义。

The responsibility weight system for renewable energy accommodation and the construction of power spot market are being implemented simultaneously in China.In order to coordinate the relationship between the conventional power trading varieties and the accommodation responsibility weight trading varieties and to realize the smooth implementation of the accommodation weight system,we designed a market mechanism of renewable energy accommodation weight under the spot market environment.Based on an analysis of the difficulties in implementation of the accommodation weight system under the background of spot market,relevant market mechanisms are designed from four aspects,including main market players,transaction varieties,transaction mode and cycle,and transaction process.A market design of power grid player-included excessive accommodation is innovatively put forward.A case study demonstrates the positive significance of the power grid player-included excessive accommodation market in promoting the development of new energy.
