摘要

绿电交易是推动能源绿色低碳转型的重要手段。中国电力市场当前普遍采用绿电-常规电力或电能量-环境属性的顺次分平台出清方式，难以保证常规电力与绿电交易的整体社会福利最大，导致市场资源配置效果欠佳。为此，提出了面向整体社会福利最优的绿电-常规电力同台出清方法。首先，将绿电交易拆解为电能量和环境属性两类商品，并构建了两类商品分开申报、同台竞争的绿电-常规电力出清模式。其次，构建了以电能量与环境属性整体社会福利最优为目标、涵盖两类商品供需平衡与相互耦合约束的绿电-常规电力同台出清模型，并剖析了该模型相较于顺次分平台出清模型的优势。然后，提出了绿电-常规电力同台出清的定价结算机制，可实现绿电价格的科学分解，并从理论上证明了该机制满足市场主体成本回收性质。最后，通过算例分析验证了所提方法能够有效提升整体社会福利，并将绿电总价合理分解为电能量价格与环境价格。

Abstract

Green power trading is an important means to promote green and low-carbon energy transition. The current electricity market in China generally adopts the sequential separate-platform clearing mode of green power-conventional power or electric energy-environmental attributes

which makes it difficult to maximize the overall social welfare of conventional power and green power trading

resulting in unsatisfactory market resource allocation. Therefore

a unified-platform market clearing method of green power and conventional power for optimal overall social welfare is proposed. Firstly

the green power trading is decomposed into two types of commodities

i.e.

electric energy and environmental attributes. A market clearing mode of green power and conventional power is also constructed

in which the two types of commodities are declared separately and compete on a unified platform. Secondly

a unified-platform market clearing model of green power and conventional power

which takes the optimal overall social welfare of electric energy and environmental attributes as its objective and covers supply-demand balance and mutual coupling constraints of the two types of commodities

is constructed

and the advantages of this model over the sequential separate-platform clearing model are analyzed. Then

the pricing and settlement mechanism for the unified-platform market clearing of green power and conventional power is proposed

which can realize the scientific decomposition of green power price. It is theoretically proven that this mechanism satisfies the cost-recovery property for market participants. Finally

case studies verify that the proposed method can effectively improve the overall social welfare and reasonably decompose the total green power price into electric energy price and environmental price.
