摘　　要：在大规模光伏接入的现状下,存量配电网与增量配电网存在有功/无功调节手段差异。本研究兼顾差异化的配电网现状及需求,设计了双层优化调度框架,外层对应日前阶段,基于日前负荷及分布式光伏发电预测,通过协调慢调节设备动作量,进行目标为经济性最优的优化调度,调度间隔为1小时。内层针对实时运行阶段,调度间隔为5分钟,通过协调分布式光伏、储能及负荷响应的有功无功输出,并计及大规模分布式光伏预测出力偏差风险,实现以网损及未来节点电压偏差风险最小,和灵活调节手段调节最小为目标的实时优化调度。采用改进的IEEE 33节点算例在多个场景下验证了方法的有效性。Under the current situation of large-scale photovoltaic integration,there are differences in active/reactive power regulation means between the existing distribution network and the incremental distribution network.Taking into account the current situation and requirements of the differentiated distribution networks,this study has designed a two-layer optimal dispatching framework.The outer layer corresponds to the day-ahead stage.Based on the day-ahead load and distributed photovoltaic power generation forecasts,through coordinating the action amounts of slow regulation equipment,an optimal dispatching with the goal of achieving the best economic performance is carried out,and the dispatching interval is one hour.The inner layer is for the real-time operation stage,with a dispatching interval of five minutes.By coordinating the active and reactive power outputs of distributed photovoltaics,energy storage and load responses,and taking into account the risk of prediction output deviation of large-scale distributed photovoltaics,the real-time optimal dispatching with the goals of minimizing the network loss and the risk of future node voltage deviation,as well as minimizing the adjustment of flexible regulation means is realized.The effectiveness of the method has been verified in multiple scenarios using an improved IEEE 33-node example.
