摘　　要：当前大规模户用光伏接入低压配电网已成为必然趋势,然而高渗透率户用光伏并网将引起电压越限等严重的电压问题。在低压配电网中合理配置储能可以有效缓解上述问题,同时信息通信技术是储能消纳光伏的重要保证。针对目前信息系统和物理系统分开进行规划的现状,该文提出了一种基于二层优化模型的协同规划方法对含高比例光伏低压配电网的储能系统与通信网络进行优化配置。上层以年费用最小为目标优化配置储能和无线通信终端,其中储能采用分布式控制策略;下层根据上层的结果进一步对通信拓扑进行优化,提高控制性能的同时降低通信网络的复杂度。通过算例仿真验证了所提信息系统与物理系统协同规划方法的经济性和有效性。It is a trend at present that large scale residential PVs are integrated into low-voltage distribution networks（LVDNs）, which will cause voltage violation problems. Energy storage systems（ESSs） have recently been incorporated into LVDNs for mitigating these problems. Meanwhile, information and communication technologies are playing an important role to resolve accommodation problems of PVs. Although physical system and cyber system influence each other, they are generally configured separately in LVDNs. This paper proposes a collaborative configuration scheme based on a bi-level optimization model for ESSs and communication networks in LVDNs with high penetration of PVs. In the upper level, the ESSs and wireless control terminals are deployed to minimize annual cost with consideration of a distributed control of ESSs. In the lower level, communication topology is further optimized according to the upper level results to promote control performance and balance cyber-topology complexity. The economy and effectiveness of the proposed collaborative configuration scheme are demonstrated in case studies.
