摘要:

随着售电侧的放开,分布式发电与售电公司一同竞争形成多售电主体交易市场。现有交易模式存在过网费统一定价难以公平应对不同交易对电网运行成本的影响、集中式交易难以高效且经济的处理大量分布式交易等诸多弊端,因而建立合理的交易模式尤为重要。为此,文中探讨了动态过网费机制下多售电主体点对点交易模式。针对点对点交易小量、高频特性,建立基于灵敏度系数的动态过网费min-max问题并求解。利用连续双向拍卖的匹配机理,考虑售电主体提供的普遍-定制服务,提出计及动态过网费的2次连续双向拍卖多轮交易机制。多轮交易中,针对每一轮交易提出实时滚动的网络校核方法。考虑交易双方心理行为,提出改进型失望-后悔规避理论进行报价更新。仿真结果表明所提动态过网费机制能够针对每笔交易特性更加合理地分摊电网运行成本,且设计的点对点交易机制可安全、经济、高效地实现计及动态过网费的多边竞价交易。

Abstract:

With the liberalization of the power sales side, distributed power generation and electricity sale companies compete together to form a trading market with multiple electricity sale entities. However, existing trading model has many drawbacks. For example, the uniform pricing of network fees is difficult to fairly deal with the impact of different transactions on grid operating costs, and the centralized transaction form is difficult to efficiently and economically process a large number of distributed transactions. Therefore, it is especially important to establish a reasonable trading model. For this reason, this paper discusses the peer-to-peer transaction model of multiple electricity sellers with the dynamic network fees mechanism. Considering the small-volume and high-frequency characteristics of peer-to-peer transactions, the min-max problem of dynamic network fees based on sensitivity coefficients is established and solved. Using the matching mechanism of continuous double auction and considering the general-customized service provided by electricity sellers, the multi-round transactions mechanism of two continuous double auctions with dynamic network fees is proposed. In multi-round transactions, a real-time rolling network verification method is proposed for each round of transactions. Considering the psychological behavior of both parties to the transaction, an improved disappointment-regret avoidance theory is proposed to update the quotation. Simulation results show that the proposed dynamic network fees mechanism can allocate the operation cost of the power grid more reasonably according to the characteristics of each transaction, and the designed peer-to-peer transaction mechanism can safely, economically and efficiently realize the multilateral bidding transactions considering the dynamic network fees.
