摘　　要：虚拟电厂(virtual power plant,VPP)可以通过先进的控制技术对海量分散的分布式能源进行有效聚合,为实现低碳发展提供了有效途径。为促进VPP在碳减排方面的积极作用,提出了一种VPP联盟和配电网多主体协同优化框架。首先,基于碳排放流理论制定了电-碳综合定价方法,激励VPP低碳运行。其次,考虑多个VPP之间采用合作联盟的形式进行共享交易,构建一种基于纳什议价理论的多VPP电碳点对点(peer-to-peer,P2P)交易机制模型,实现资源共享的同时兼顾个体利益和联盟效益。在此基础上,建立一种基于电-碳综合价格引导VPP间电碳P2P交易的VPP联盟-配电网协同优化双层模型。上层模型是多VPP之间电碳P2P最优交易问题,采用自适应步长交替方向乘子法实现多VPP间的分布式求解。下层模型则是配电网的最优经济调度问题。最后,通过算例验证了所提模型和方法的有效性。A virtual power plant(VPP)can effectively integrate massive and scattered distributed energy resources through advanced control technology,effectively achieving low-carbon development.To promote the positive role of VPP in carbon emission reduction.This paper proposed a multi-agent collaborative optimization framework for the VPP alliance and distribution network.Firstly,based on the carbon emission flow theory,a comprehensive electricity-carbon pricing method was developed to incentivize the low-carbon operation of VPP.Secondly,considering that multiple VPPs used the form of cooperative alliance to share transactions,this paper constructed a multi-VPP electricity carbon peer-to-peer(P2P)trading mechanism model based on Nash bargaining theory,which realized multi-VPP resource sharing and considered individual interests and alliance benefits.This paper constructed a bi-level model of VPP alliance-distribution network collaborative optimization based on the comprehensive price of electricity and carbon to guide the P2P transaction between VPPs.The upper-level model was the optimal transaction of electricity and carbon P2P between multiple VPPs.The adaptive step size alternating direction method of multipliers was used to realize the distributed solution between multiple VPPs.The lower-level model was the optimal economic dispatch problem of the distribution network.Finally,an example was given to verify the effectiveness of the proposed model and method.
