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。Multiple virtual power plants（VPP） can work together to participate in electricity market and get earnings through joint bidding.A scheduling-allocation cycle can be divided into scheduling day,execution day and allocation day.Uncertainty of market price and intermittent power generation can be dealt with multi-scenarios method in scheduling day.Goal of joint bidding is to maximize sum of bidding earnings in day-ahead market and rewards in balance market.The alliance must bear certain rewards/punishments because of deviation of actual output from forecast expectations of intermittent power generation in execution day.VPP can be divided into VPPs with controllable and intermittent generations.To study whether multiple VPP joint scheduling is beneficial to individuality,an approach of earnings and reward/punishment allocation based on their different characteristics is raised and an evaluation method based on reward/punishment allocation expectation is put forward.Finally,feasibility and rationality of the proposed allocation and evaluation method is verified with different actual examples of VPP combination.
