摘　　要：提出了一种基于随机潮流计算的分布式光伏选址定容研究的新方法。将多目标函数设为成本、网损、电压稳定性三个方面,对并网的光伏出力及配电网自身的负荷进行随机性建模,采用半不变量法来减少整体方案计算所需的时间。最后通过仿真分析,验证了最优的光伏并网位置及容量能够有效地改善配电网的网络损耗和电压越限,提高配电网的电压质量,使配电网运行处于最佳状态。This paper presents a new method for distributed photovoltaic(PV) site selection and sizing based on stochastic power flow calculations.Firstly,the multi-objective function is set as cost,network loss and voltage stability.Secondly,the random modeling of grid-connected PV output and the load of distribution network is carried out.In addition,the semi-invariant method is used to reduce the time required for the calculation of the whole scheme.Finally,through simulation analysis,it is verified that the optimal PV grid-connected location and capacity can effectively improve the network loss and voltage overlimit of the distribution network,improve the voltage quality of the distribution network,and make the distribution network operate in the best state.
