分布式发电微电网簇的同步稳定性
Synchronization stability of distributed generation microgrids cluster
摘要
Abstract
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.关键词
