摘要
配电中接入的分布式电源的增多,潮流计算时,传统的前推回代法无法满足精度要求.对系统研究发现,分布式电源的出力和接入位置对配电网的网损有不同的影响,阐述了分布式电源潮流计算模型,并引入了一种带有PV节点无功修正的分布式电源配电网潮流计算方法.通过对IEEE14节点系统进行仿真验证,证明了所提算法的有效性和收敛性.研究结果显示:新提出的方案和技术能够更加高效地解决带有分布式电源的配电网潮流问题.
Abstract
With the increase of distributed power supply in distribution,the traditional forward and backward sweep algorithm can not meet the accuracy requirements in power load flow calculation.It is found that the output and access location of distributed power sources have different effects on the network loss of distribution network.The power load flow calculation model of distributed generation is expounded,and a power load flow calculation method of distributed generation distribution network with PV node reactive power correction is introduced.The effectiveness and convergence of the proposed algorithm are proved by the simulation of IEEE14 node system.The research results show that the new proposed scheme and technology can solve the power flow problem of distribu-tion network with distributed generation more efficiently.
