摘　　要：微电网规模随着新能源渗透比例的提高与日剧增,然而由于缺乏灵活的能量转移机制,针对单个微电网的低碳经济调度优化效果有限。有效利用多微网系统内部的结构差异,实现能源在空间与时间双重维度上的流动对促进新能源电力系统低碳经济发展具有重要意义。为此,该文在考虑多微网功能区差异的基础上,运用纳什谈判思想,制定了计及电、热、碳能源交易的多微网系统优化调度策略。首先,针对微网功能区差异性构建基于居民区、商业区与工业区的多微网系统运行框架;其次,根据不同功能区的负荷特性构建了计及电、热负荷可替代性的需求响应模型;最后,以纳什谈判思想为基础,结合交替方向乘子法与商业求解器达成多微网间电、热、碳互利共赢的交易策略。算例分析验证了所提方案能够在实现多微网隐私保护的前提下全面提高系统运行的低碳性与经济性。The scale of microgrids increases sharply with the rising of the proportion of new energy penetration,but due to the lack of flexible energy transferring mechanisms,the optimization effect of low-carbon dispatching for individual microgrids is limited.It is of great significance that the structural differences of heterogeneous microgrids are utilized to make the energy flowing in the dual dimensions of space and time,so that the reduction of carbon emissions of renewable energy power systems can be promoted.Therefore,considering the differences in the functional areas among the microgrids,an optimal dispatch of multi-microgrid systems considering electricity-heat-carbon trades is constructed by adopting the Nash’s negotiation ideas.Firstly,according to the differences in functional microgrids,an operation framework of multi-microgrids system based on the residential,commercial and industrial microgrids is constructed.Secondly,taking into account the load characteristics of different microgrids,a demand-response model considering the alternative of electricity and heat loads is built.Finally,based on the Nash’s negotiation,and combined with the alternating direction multiplier method and the commercial solver,a mutually beneficial and win-win trading strategy of electricity,heat and carbon among multi-microgrids is reached.The case analysis verifies that the proposed method is able to comprehensively improve the environmental and economical benefits of the multi-microgrids under the premise of realizing privacy protection.
