摘要由于可再生能源出力的间歇性与随机性给配电网电压控制带来了挑战,因此本文提出了一种考虑微电网参与的主动配电网（ADN）无功电压分区与控制策略。通过潮流计算,获得电压灵敏度矩阵,采用聚类算法构建分布式微电网在ADN中的控制空间,确定微电网主导的可控区域集合。在自动电压控制（AVC）系统的框架上,提出了考虑微电网参与电压柔性控制的AVC系统。通过该系统可合理调度微电网与传统无功补偿设备协调运行,并对ADN进行无功补偿,实现控制区域柔性且快速的自动电压控制,提升ADN电压质量。最后,通过IEEE 33节点系统验证了所提策略的有效性。

Abstract：The intermittence and randomness of renewable energy output poses challenges to voltage control of distribution network. In this paper, an active distribution network (ADN) reactive voltage partition and control strategy considering microgrid participation is proposed. Firstly, through the power flow calculation, the sensitivity matrix of node voltages is obtained, and condensed clustering algorithm is used to build the control space of microgrid in ADN, which can determine the cluster of controllable nodes dominated by the microgrid. Then, under the framework of the classic automatic voltage control (AVC) system, a new AVC system with participation of the microgrid in flexible and fast voltage control is proposed. The developed AVC system can coordinate the operation microgrid and conventional reactive compensation equipment, realizing quick and flexible voltage control and improving the quality of voltage of ADN. Finally, a simulation model based on IEEE 33-node system is established. The simulation results verify the proposed voltage control strategy.
