| 中文摘要:提出一种分布式电压控制策略，基于分布式电源（distributed generation，DG）集群实现含高比例DG接入的配电网电压控制。通过对DG集群主导节点与DG容量利用比的计算，建立起节点电压与DG出力之间的定量关系，进而对相关变量进行整定计算。最后，通过仿真软件搭建IEEE 33节点配电网辐射状接线模型与环网状接线模型，验证了所提分布式电压控制策略可以实现配电网不同负载情况、不同接线模式下全局电压良好分布。 |

| Abstract:This paper presents a distributed voltage control strategy， by which the voltage control of the network containing a high proportion of distribution generation access is realized based on the distributed generation cluster. The quantitative relationship between the node voltage and the DG power output is established by calculating the capacity utilization ratio between the dominant node and the distributed generation cluster， and then the setting calculation of the relevant variables is performed. Finally， a radial connection model and a ring-mesh network connection model of IEEE 33-node distribution network are established by simulation， and it is verified that the proposed distributed voltage control strategy can realize good global voltage distribution of the distribution network under different load conditions and different connection modes. |
