摘要: 分布式电站相互连接,形成分布式电站网络,在分布式电站网络中,也有着不同的组成结构,这些结构就是一个小子网,本文称之为分布式电站子网。本文首先提取分布式电站网络中3种基本的组成结构进行研究,分别为线形结构、环形结构和星形结构;然后对比3种不同结构的分布式电站子网接入IEEE30及IEEE57系统下的网络平均距离及同步能力,发现在3种分布式电站子网中,星形分布式电站子网的中心节点接入电网时,网络平均距离最小且同步能力最好;最后将分布式电站连接为类星形的BA分布式电站网络,并接入电网中进行研究。研究发现:第一,随着分布式电站网络规模的扩大,将分布式电站网络接入电网使得网络平均距离增大,并且对电网的同步能力会产生不利的影响;第二,随着BA分布式电站网络与配电网之间的连边数不断增加,使得网络平均距离减小,并且网络临界耦合强度在不断减小,并最终趋向一个稳定值。

Abstract: Distributed power stations are interconnected to form a distributed power station network. In a distributed power station network, there are also different compositional structures. These structures are small subnets, which is called distributed power station subnets. Firstly, the three basic structures including linear structure, circular structure and star structure are studied in distributed power grid network. Next each subnet of the three different structures is respectively connected to IEEE30 and IEEE57 system. It is found that in the three distributed power station subnets, when the central node of the star distributed power station subnet is connected to the power grid, the network average distance is the smallest and the network synchronizability is the best, which shows that the star structure is best suited as a substation structure of a distributed power station subnet. Subsequently, the distributed power stations are connected as a star-like BA distributed power station subnet and are connected to the grid. It is found that with the expansion of the subnet scale of the distributed power stations, the average distance of the network will increase and the synchronizability of the power grid will be weakened. Meanwhile with the increasing of edges between the distributed power station subnet and the power grid, the network average distance decreases and the network synchronizability gets better and finally tends to a stable value.

Key words: distributed power station, distributed power station network, network average distance, synchronizability, critical coupling strength
