首先介绍解决配电网双向潮流的方向保护和防孤岛保护的3个基本类型(被动保护、主动保护、广域保护),以避免可再生能源高渗透率条件下出现的故障保护和非计划孤岛问题.针对客户跟随电源的运行模式,讨论了客户参与主动控制的多种可能性,特别讨论了主动客户给市场与电网带来的影响.针对配电网规划需要考虑网络控制问题这一全新概念,分析了网络控制中网络解与非网络解的作用,并以无功电压优化控制为例介绍了新的控制方式.

In the paper,directional protections are introduced as the solutions of the fault protection in the case of bidirectional power flow in distribution network and three basic types of anti-islanding protection(passive protection, active protection,and protection basedon communication network) as solutions of anti-unintentional islanding with a high penetration of DG.For the operation in which demand responds the energy resource,various possibilities of customers to participate in active control of the grid are presented,especially the influences of active users to power grid and power market are discussed.Based on the new concept that network control should be taken into consideration in distribution network planning,the paper discusses the impacts of network and non-network solutions in network control,and new types of control approachs are illustrated by the Var/Vol optimal control in distribution network.
