考虑需求响应的虚拟电厂两阶段市场竞标模型
摘要：虚拟电厂为大规模新能源电力涌入电网提供框架和技术支撑的同时，也为其参与电力市场提供了保障，因此为虚拟电厂建立经济可靠的竞标模型是当前研究的热点。在双结算模式与偏差考核的背景之下，提出了考虑激励型需求响应参与的虚拟电厂竞标模型。考虑在日前与实时市场、当前实时与后续实时市场的双重耦合下，得到虚拟电厂的日前与实时竞标策略；并提出“双因素激励因子”的概念，调动实时需求响应的积极性，减小虚拟电厂的偏差惩罚的同时也可以利用价差获利。最后，以38节点的RBTS配电系统为例进行仿真，仿真结果表明该策略在充分挖掘用户需求响应潜力的同时，提高了虚拟电厂的经济效益，为虚拟电厂参与电力现货市场提供了模型参考。
Abstract:Virtual power plants provide framework and technical support for large-scale new energy power pouring into the power grid, meanwhile they also provide the security for themselves participating electricity market. For this reason, it becomes a hot research topic to establish an economical and reliable bidding model for virtual power plants. Under the background of double settlement mode and deviation assessment, a bidding model of the virtual power plant, in which the participation of incentive demand response was taken into account, was proposed. Considering the coupling of day-ahead market and realtime market and that of current realtime market and follow-up real-time market, the day-ahead and realtime bidding strategies of virtual power plant were obtained. Besides, the concept of dual-factor excitation factor was proposed to motivate the positivity of realtime demand response and to reduce the deviation of punishment of virtual power plant, at the same time the price difference could also be taken to make profit. Finally, the simulation result of a 38-bus RBTS distribution system show that while the potential of users’ demand response is fully tapped, by use of the proposed bidding strategy the economic benefit of virtual power plant could be improved. The proposed model provides reference for virtual power plant participating in electricity spot market.
