Abstract:

在分析了几种常见分布式电源(distributedgeneration,DG)并网类型和出力特性的基础上,对其中3类具有调节能力的分布式电源的并网位置和运行出力进行了综合优化,以使配电网的网络损耗降到最小。对所提优化模型变量进行了分离处理,形成了交叉反馈粒子群算法(crossfeedbackparticleswarmoptimizationalgorithm,CFPSO)。对比了基于分离变量思想的分层嵌套粒子群算法(layerembeddedparticleswarmoptimizationalgorithm,LEPSO)。以某三馈线配电系统为例对提出的模型进行了仿真计算,计算结果验证了2种算法的有效性。由于实现了变量的完全解耦以及反馈机制的引入,CFPSO算法具有更好的收敛精度,同时大大提高了求解效率。
