分布式发电微电网簇的同步稳定性OACSTPCD
Synchronization stability of distributed generation microgrids cluster
对分布式发电多小区微电网组成的簇网络的同步稳定性进行了研究.基于电力网络常用三种模型星型、树型以及环型网络以及改造后的新型蛛网结构,对网络的拓扑结构和网络特性间的内在联系进行了深入研究,对影响系统同步稳定性的因素进行了分析.以复杂网络图论和Kuramoto振子模型为基础,构建簇网络模型,通过观察该集群网络相关参数的变化,分析子网互联程度对整个网络同步性能的影响.结果表明:分散式连接方式比较集中式连接方式构成的簇网络同步性能更好;簇网络的各子网间联系越密切,所形成的簇网络拥有越好的同步性能;分析子网间连接边的连接强度,结果显示连接强度的增加有利于整个网络的稳定,而对子网络同步稳定性有更加复杂的影响.
The synchronous stability of cluster networks composed of distributed generation multi-cell microgrids is stud-ied.Based on three commonly used models of power network,namely star,tree and ring network,as well as the new cob-web structure after modification,the internal relationship between network topology and network characteristics is deeply studied,and the factors affecting system synchronization stability are analyzed.Based on the complex network graph theory and the Kuramoto oscillator model,the cluster network model is constructed.By observing the changes of the relevant pa-rameters of the cluster network,the influence of the degree of subnet interconnection on the synchronization performance of the whole network is analyzed.The results show that the decentralized connection mode has better synchronization per-formance than the centralized connection mode.The closer the connections among the subnets of the cluster network,the better the synchronization performance of the cluster network.The results show that the increase of the connection strength is beneficial to the stability of the whole network,as well as has more complex influence on the synchronization stability of the sub-network.
