【摘要】：多个虚拟发电厂(virtual power plant,VPP)可以合作参与电力市场,通过联合竞标获得收益。将VPP的一个调度?分配周期分为调度日、执行日和分配日,调度日中采用多场景法处理日前市场电价和间歇性电源的不确定性,以VPP联盟在日前市场的竞标收益和平衡市场受到的奖惩之和最大为目标进行联合竞标;执行日中由于间歇性电源实际出力与预测期望之间存在偏差,联盟需承担一定的奖惩。将VPP划分为纯可控类VPP和含间歇性电源类VPP,为研究各类VPP联合调度对VPP个体是否有利,提出了基于各自不同特点的收益及奖惩的分摊方法和基于奖惩分摊期望的利害评判方法,并通过不同VPP组合的实际算例,验证了所提分摊方法和评判方法的可行性和合理性。
[Abstract]:Multiple virtual power plants, virtual power plans, can collaborate to participate in the electricity market and make profits through joint bidding. Schedule a VPP? The allocation period is divided into scheduling day, execution day and distribution day. In scheduling day, multi-scenario method is used to deal with the uncertainty of market price and intermittent power supply. Aiming at the maximum sum of rewards and penalties received by the VPP alliance in the pre-day market and the maximum sum of the rewards and penalties received in the market, the alliance should bear certain rewards and punishments due to the deviation between the actual output of the intermittent power supply and the forecast expectation in the execution day. The VPP is divided into pure controllable VPP and VPP with intermittent power supply. In order to study whether each kind of VPP joint scheduling is beneficial to the individual of VPP, this paper puts forward a method of allocation of income, rewards and punishments based on their own characteristics, and a method of evaluating interests based on the expectation of reward and punishment sharing. The feasibility and rationality of the proposed allocation method and evaluation method are verified by practical examples of different VPP combinations.
