摘　　要：随着增量配网改革大量微能网接入系统,形成具有多微能网的城市能源互联网,给城市能源互联网调度带来了巨大的风险。针对多个微能网接入城市能源互联网造成的多方利益交互与调控运行的问题,提出一种含多微能网的城市能源互联网优化调度策略。构建了微能网与综合能源运营商交互协调机制,采用分布式建模方法,建立了各微能网和综合能源运营商的经济优化目标,并提出了多微能网与综合能源运营商协调优化的调度策略。算例表明所提调度策略保证了微能网信息的私密性,提升了微能网的主动性,改善电力与天然气系统互联互济的水平,减小了城市能源互联网用电负荷的峰谷差,实现了各微能网与综合能源运营商互利共赢。As the incremental distribution network reforms,a large number of micro-energy network access systems,the formation of an urban energy internet with multiple micro-energy networks has brought huge risks to the urban energy internet dispatch.Aiming at the problem of multi-party interest interaction and regulation operation caused by multiple micro-energy networks connected to the urban energy internet,we propose an optimal scheduling strategy for an integrated energy system with multi-micro energy grids.The interaction and coordination mechanism between the micro-energy network and the main network is constructed,and the distributed modeling method is adopted to establish the economic optimization goals of each micro-energy network and the main network.Moerover,a scheduling strategy for the coordination and optimization of the multi-micro energy network and the main network is proposed.The calculation example shows that the dispatch strategy proposed in this paper guarantees the privacy of the micro-energy network information,improves the initiative of the micro-energy network,improves the level of interconnection and mutual benefit between the power and natural gas systems,and reduces the peak load of the urban energy internet.The valley gap has achieved mutual benefit and win-win results for all micro-energy networks and integrated energy operators.
