摘　　要：为了探究分布式光伏并网容量和接入位置对低压台区线损的影响,构建含分布式光伏的低压台区多场景仿真模型,并分析线损影响因素。分别搭建两级式光伏逆变仿真模型和15节点低压馈线模型,用以模拟三相负荷不平衡情形下的实际电网运行情况。实现光伏和15节点低压馈线模型的并网运行,分析光伏不同接入位置和不同接入容量等多场景下的线损变化规律,为分布式光伏的选址定容和低压台区降损节能提供决策支持。In order to explore the influence of the grid-connected capacity and access location of distributed photovoltaic(PV)on the line loss of low-voltage distribution station area,a multi-scene simulation model of low-voltage distribution station area with distributed PV is built,and influencing factors of line loss are analyzed.A two-stage PV inverter simulation model and a 15-node low-voltage feeder model are built respectively to simulate the actual power grid operation under the three-phase unbalanced load.The grid-connected operation of PV and 15-node model is realized,and the line loss variation rule under different PV access locations and different access capacities is analyzed,which can provide decision support for the location and capacity determination of distributed PV,the loss reduction and energy saving of low-voltage distribution station area.
