摘要对分布式电源实施主动管理可以减小其出力间歇性和随机性给配电网造成的负面影响,但这也对配电网的电压控制提出了更高的要求。首先介绍了主动配电网电压控制的特点,采用图论对主动配电网的网络结构进行描述。提出了主动配电网双阶段电压控制方法,该方法是通过优化系统中各分布式电源的无功出力共同协作将电压控制在规定范围内。最后,在8节点和30节点配电系统验证了所提方法的有效性和实用性。

Abstract：Active management used on distributed energy resources (DERs) can reduce the negative effect caused by the intermittent and randomness of its power output, but it also puts forward higher requirements on the voltage control in the distribution network at the same time. In this paper, the characteristics of voltage control of active distribution network are introduced at the beginning, the network structure of active distribution network is described by graph theory. A dual-stage voltage control method in active distribution networks is put forward, which regulates the voltage within specified range by optimizing reactive power output of different DERs in the system. Finally, the effectiveness and practicability of the proposed method are verified by case studies in 8- bus and 30-bus distribution systems.

Key words： Distributed energy resources voltage control active distribution network graph theory
