摘　　要：阐述了分布式电源的分类,介绍了4种常见的分布式电源发电形式和发展状况。建立了接入和未接入分布式电源2种理想化的配电网系统模型,研究分析后可得到分布式电源的接入位置、接入容量和功率因数是影响配电网系统网络损耗的重要因素。最后基于PSASP7.0的环境建立IEEE 33节点配电网系统仿真模型,运用单一变量法进行仿真并对结果进行整理,验证分布式电源的改变会导致网络损耗的变化,选择恰当的数据会降低配电网系统的网络损耗。The classification of distributed power sources is described.Four common forms of distributed power generation and the current development status are introduced.Two ideal distribution network system models with and without distributed power supply are established.Through research and analysis,it can be concluded that the access location,access capacity and power factor of the distributed power supply are important factors affecting the network loss of the distribution network system.Finally,the simulation model of the IEEE 33-node distribution network system is established based on the PSASP7.0 environment,and the single variable method is used to implement the simulation.and organize the results.The results are summarized to verify that the change of distributed power will lead to the change of the distribution network loss,and the selection of appropriate data will reduce the network loss of the distribution network system.
