摘　　要：虚拟电厂可通过资源互补提升潜在收益,但也面临合作联盟规模、主体利益保障及主体隐私保护3个关键问题。首先证明了虚拟电厂合作博弈的存在性以及主体理性假设下合作联盟整体参与市场的唯一性。其次基于非对称纳什议价方法,提出了以净功率输出为贡献度进行度量的合作收益分配机制,保障合作联盟稳定性。然后计及各虚拟电厂的隐私保护需求,提出了dual-block交替方向乘子法(ADMM)分布式求解方法,避免多主体ADMM迭代引起的收敛性问题。最后通过算例验证了所提合作收益机制的有效性和分布式求解算法的高效性。Virtual power plants(VPPs)can jointly improve the potential revenue by using complementary resources.However,the joint operation also faces three major problems,including the scale of alliance,individual revenue pro-tection,and individual privacy preservation.Targeting these problems,this paper firstly proves the existence of the cooperative game of VPPs and the uniqueness of the alliance composed of all VPPs under the assumption of individual rationality.Then based on the asymmetric Nash bargaining theory,this paper proposes a cooperation revenue allocation mechanism that adopts the net power output as the contribution index,guaranteeing the stability of the alliance.Considering the privacy preservation requirement of the clustered VPPs,a dual-block alternating direction method of multipliers(ADMM)algorithm is proposed to avoid the convergence problem in the multi-agent ADMM algorithm.By conducting numerical tests,the effectiveness of the proposed alliance strategy and revenue allocation mechanism and the efficiency of the dual-block ADMM algorithm are verified.
