摘　　要：具有随机性和波动性等特征的分布式光伏规模化接入配电网,给配电网安全可靠运行带来了新的技术难题。为评估并提升配电网分布式光伏最大准入容量,提出了计及5G基站可调特性的配电网分布式光伏准入容量鲁棒优化方法。首先,构建了计及通信负载迁移和储能动态备电的5G基站可调特性模型;其次,建立了含5G基站的配电网分布式光伏最大准入容量鲁棒优化模型;然后,采用渐紧线切割算法和列与约束生成算法相结合的方法求解模型;最后,在改进的IEEE 33节点配电网上验证了模型的有效性,分析了“源-荷”不确定性、5G基站通信负载迁移和储能动态备电对配电网分布式光伏最大准入容量的影响。With distributed photovoltaics access massively,which is characterized by stochasticity and volatility,has posed new technical challenges to the safe and reliable operation of the distribution network.To evaluate and improve the hosting capacity of distributed photovoltaics in distribution network,the article proposed a robust optimization method for the hosting capacity of distributed photovoltaics in the distribution network,which considers adjustable characteristics of 5G base stations.Firstly,a 5G base station adjustable characteristics model is constructed,which considers the communication load migration and the dynamic power backup of the energy storage.Secondly,a robust optimization model of the maximum hosting capacity of distributed photovoltaics in the distribution network with 5G base stations is established.Then,the model is solved using an increasingly tight linear cut algorithm combined with a column-and-constraint generation algorithm.Finally,the effectiveness of the model is verified on an improved IEEE 33-node distribution network,and the effects of source-load uncertainty,5G base station communication load migration,and dynamic energy storage backup on the maximum access capacity of distributed photovoltaics in distribution network are analyzed.
