计及分布式发电的配电网潮流计算

摘要

There is a great impact on the stability of the system when DG（distributed generation） is introduced to distribution network.This paper analyzes some common DG and proposes their models in power flow calculations,and take the forward-backward sweep method to calculate.Considered the weak capability of the forward-backward sweep method disposing PV nodes,a new method,compensation of injecting reactive power,is tested in the 33-node system of distributed network,and the result shows the method is effective.%分布式电源的并网对配电系统的稳定性有着重要影响。分析了几种常见的分布式电源（DG）,建立潮流模型,采用前推回代法进行潮流计算。鉴于前推回代法处理PV节点的能力较弱,对PV节点进行无功补偿修正,通过在33节点配电系统算例进行测试,结果表明该方法是可行的。
