摘　　要：分布式发电的协调控制与管理为主动配电网的主动电压调节提供了更多的技术手段,使得主动配电网的电压协调控制成为可能。分析了分布式发电对于现有配电网电压水平及其控制策略的影响,在此基础上研究并提出了主动配电网的电压分层协调控制体系及其策略。一方面利用馈线电压的精准估算,通过闭环控制逻辑实现单条馈线的电压水平实时控制,并设计了相应的主动配电网电压协调控制器;另一方面借助变电站变压器的分接头调节和电容器投切协调多馈线的电压水平,确保配网的电压质量。针对一个双馈线主动配电网的仿真试验验证了所提控制策略的有效性及实用性。The coordinated control and management of distributed generators in active distribution network （ADN） provide distributionsystem operators with more approaches to control voltage actively and make coordinated voltage control（CVC） possible in ADN. Theimpacts of distributed generators on existing voltage level and control strategies of distribution network are analyzed, based on which ahierarchical CVC framework and corresponding trategy of ADN are proposed. On one hand, the closed loop voltage control of singlefeeder is realized by means of CVC controller on the basis of accurate voltage estimation, on the other hand, transformer tap adjustingand capacitor switching are employed to ensure the voltage level and quality of multiple feeders. The effectiveness and practicability ofthe proposed CVC strategy are verified on a 2 - feeder ADN.
