摘要： 分布式电站的引入增加了电网的复杂性,对电网的稳定性和抗扰性等性能造成不确定性的影响。本文提出分布式电站的3种入网方式,并对3种入网方式下电网的拓扑特性、同步性能和抗扰性能进行比较研究。入网方式1:令新增加分布式电站直接与电网的负载节点相连(称为SC入网方式);入网方式2:在方式1的基础上,邻近分布式电站之间彼此连接(称为LC入网方式);入网方式3:同样在方式1的基础上,邻近分布式电站之间以概率p相连接(称为PC入网方式)。研究表明:3种入网方式中,LC入网方式电网的同步性能和抗扰性能最好,SC入网方式电网的同步性能和抗扰性能最差,PC入网方式电网的同步性能和抗扰性能位于其他2种方式之间。本文研究可为未来智能电网系统的构建提供理论参考。

Abstract: The introduction of distributed power supply increases the complexity of the power grid, which causes some problems such as the stability and immunity of the power grid. In this paper, three types of distributed power plant connection strategies are proposed, and the topological characteristics, synchronization performance and disturbance rejection ability of a grid with the three types of connection strategies are compared. Mode 1 directly connects a new increasing distributed power plant with a load node (named the SC mode), Mode 2 is based on the way 1, and connects the nearby distributed power plant (named the LC mode). Mode 3 is also based on the way 1, connecting the nearby distributed plant with a certain probability (named the PC mode). Study shows that the synchronizability and anti-interference performance of a grid with the LC mode are the best among the three types of connection strategies, while the synchronization and anti-interference performance of a grid with the SC mode are the worst. The performace of the PC mode is better than that of the SC mode but is worse than that of LC mode.The study provides a theoretical reference for the future construction of smart grid system.

Key words: the distributed power plant, synchronization performance, network access mode, anti-interference performance
