摘　　要：智能电网框架下,清洁能源的友好接入、实现节能减排和减少环境污染,是建设智能电网的标志性特征.光伏电站的并网,虽然会对电网带来一定冲击,但同时也对配电网线损率的降低有一定的促进作用.忽略其他的影响因素,仅从满足电压约束的角度,分析了光伏电站不同并网位置和并网容量对配电网线损率的影响.结果表明:光伏电源接入,随着容量的增大,系统的网损呈现先减小后增大的变化趋势.In the Smart-grid framework,to achieve the smooth access of clean energy,emission reduction and energy conservation and curbing environment pollution is the symbol of Smart-grid construction.Despite the impact to the grid,the combination of PV plant improves the line loss rate of distribution network.Neglecting the other influencing factors,we analyze the influence,from the point of voltage constraints,of different combining location and volume of PV plants on line loss rate.The conclusion indicates that with the increasing of the volume of combined PV power,the system＇s loss rate will decline firstly and then climb up.
