摘要:
      分布式电源大量融入配电网后,基于分布式电源孤岛运行成为配电网故障处理的一种重要方式,其中孤岛划分是实现分布式电源孤岛运行的关键。文中从孤岛控制方式以及多时间段有功平衡这两个角度对有源配电网孤岛划分问题进行了研究。介绍了孤岛控制方式研究情况,综合考虑了分布式电源出力间歇性和负荷需求波动性,建立了基于风光荷功率曲线的孤岛风险评估模型;提出了多时段动态孤岛划分方法,该方法实现了恢复负荷最大化,同时也考虑了孤岛内控制方式,为实现工程化奠定基础。对一典型含风光储配电网算例进行了仿真,仿真结果表明了所述动态孤岛划分方法的可行性和有效性。
Abstract:
      With the access of a large number of renewable generators to distribution network, the distributed generators based islanding operation has become an important way for the distribution network fault processing. The islanding is the key to realizing islanding operation of distributed generators. The problem of active network islanding is studied from two angles, one the multi-period active power balance and the other the island control mode. Firstly, the research situation of island control mode is put forward. Secondly, considering intermittent distributed power supply and the fluctuation of load demands, an island risk assessment model based on the wind load power curve is established. Then the multi-period dynamic island dividing method is proposed, which can achieve maximizing recovered load while taking into account the island control mode. This method lays the foundation for the realization of the project. Simulation results of a typical distribution network with wind power show the feasibility and effectiveness of the dynamic island dividing method.
