基于改进Shapley值分配的电采暖负荷群交易机制

Electric Heating Load Group Transaction Mechanism Based on Improved Shapley Value Allocation

在“双碳”目标导向下,我国新能源总装机容量逐年攀升,新能源消纳问题凸显。随着电力市场改革日益推进,电采暖等中小负荷可以通过聚合参与电力市场交易,推动源荷互动,促进新能源消纳。文章在日前市场,以风电场作为发电商,以电采暖负荷聚集商作为需求侧,根据热惯性时间长短分别提供分段报量报价曲线,采用排序法在交易中心对电量电价进行双边交易,并利用改进Shapley值法综合考虑用户经济性和舒适性,根据个人满意度对成交电量在需求侧进行合理分配。最后,通过算例验证了文章所提方法的有效性。结果表明,所提方法能够协调源荷效益,实现社会福利最大化;同时兼顾用户舒适性与经济性,提高社会整体满意度。

Under the guidance of the double carbon goal,the total installed capacity of new energy in China has been increasing year by year,and the problem of new energy consumption has become prominent.With the increasing reform of the electricity market,small and medium loads such as electric heating can participate in electricity market transactions through aggregation,promote source-load interaction,and promote new energy consumption.In this paper,in the day-ahead market,wind farms are used as power generators,and electric heating load aggregators are used as demand side.According to the length of thermal inertia time,the segmented bidding curves of are provided.The sorting method is used to conduct bilateral transactions of electricity prices in the trading center.The improved Shapley value method is used to comprehensively consider the user's economy and comfort,and reasonably allocate the transaction electricity on the demand side according to the personal satisfaction.Finally,the effectiveness of the method proposed in this paper is verified by an example.The results show that the method proposed in this paper can coordinate the benefits of source and load to maximize social welfare;at the same time,it can improve the overall satisfaction of the society by taking into account the user's comfort and economy.
