摘　　要：针对高渗透率分布式光伏接入配电网导致的电压越限问题,以及传统集中式控制面临的通信延时、计算量大与控制设备过多等问题,提出一种基于集群动态划分的配电网无功电压自律-协同控制方法。首先,建立日前集中式无功电压优化模型,安排离散无功补偿设备投退计划,日内调度以节点电压偏差最小为目标建立日内无功电压滚动优化模型,结合同步型交替方向乘子法实现各集群间的分布式协调控制;然后,通过群内本地电压实时控制抑制群内节点电压的波动;最终,以改进的IEEE 33节点系统及某地实际60节点配电网为例,验证了该方法的正确性与有效性。In response to the issue of voltage overlimit caused by high-penetration distributed photovoltaic integration into distribution networks and the challenges faced by traditional centralized control,such as communication delays,large computational load,and excessive control devices,a method for reactive voltage self-regulation and coordination control in distribution networks based on cluster dynamic partition is proposed.First,a day-ahead centralized reactive voltage optimization model is established and the on/off plans for discrete reactive compensation devices are scheduled.For intra-day dispatch,an intraday reactive voltage rolling optimization model is developed with the objective of minimizing node voltage deviations,and the distributed coordination control among clusters is achieved by combining the synchronous alternating direction method of multipliers(SADMM).Then,the fluctuation of the node voltages in the cluster is suppressed by the real-time control of the intracluster local voltages.Finally,the correctness and effectiveness of the proposed method are verified by using an improved IEEE 33-node system and an actual 60-node distribution network in a certain area as cases.
