需求响应下计及电碳市场耦合的多元主体成本效益分析

Cost-Benefit Analysis of Multiple Entities Under the Coupling of Electricity and Carbon Trading Market Considering Demand Response

成本效益研究有助于了解各市场主体的效益情况和交易意愿,从而指导市场制定更加合理的交易机制。文章提出了一种需求响应(demand response, DR)下计及电碳交易市场耦合的多个市场主体的成本效益分析方法。首先将碳交易中的单位碳排放成本计入各发电机组的报价函数中进行统一出清,体现碳交易与现货市场运营的耦合;其次,考虑了需求响应下电碳耦合市场中各个主体的交易机制,提出了发电侧、用户侧、负荷聚合商、储能运营商及电网侧的成本效益分析模型。最后,对中国某省电网某实际运行日进行了算例分析,结果表明,碳排放权交易市场运作将抬高电力市场出清价格,影响相关主体的成本与效益。

Cost-benefit research helps to understand the benefits and willingness to trade of various market players, so as to guide the market to formulate a more reasonable trading mechanism. This paper proposes a cost-benefit analysis method for multiple market players considering the coupling of electricity and carbon trading markets under demand response(DR). First, the unit carbon emission cost in carbon trading is included in the quotation function of each generating unit for unified clearing, which reflects the coupling of carbon trading and spot market operations. Secondly, the transactions of various entities in the electricity-carbon coupling market under demand response are considered. A cost-benefit analysis model for the generation side, the user side, the load aggregator, the energy storage operator and the grid side is proposed. Finally, an example analysis is carried out on an actual operation day of a certain provincial power grid in China. The results show that the operation of the carbon emission trading market will raise the clearing price of the electricity market and affect the cost and benefit of the relevant entities.
