为了明确分布式光伏并网对配电网网络损耗的影响，并给出合理的分布式光伏并网规划方案，首先总结了配电网网损的计算方法，并通过真实配电网作为算例，利用DIgSILENT仿真软件建立了包含光照和温度变化模型的光伏发电系统仿真模型。利用基于分布式光伏发电特性的仿真步长多样化连续潮流计算算法，仿真分析分布式光伏并网系统在不同接入位置和不同接入容量两种情况下系统的网络损耗变化趋势，最终得到了分布式光伏接入后配电网网络损耗的变化规律。该仿真分析结果可为配电网分布式光伏项目的规划建设提供科学的参考依据。

In order to define the influence of the distributed photovoltaic grid-connection on the network loss of distribution network and give a reasonable grid-connection planning scheme of distributed photovoltaic system,the calculation method of dis-tribution network loss was summarized,and a photovoltaic power system model with light and temperature change models was es-tablished by means of DIgSILENT simulation software and an actual distribution network as an example. The network loss change trend was analyzed under the different location and penetration levels of distribution photovoltaic system by utilizing simu-lation step's diversification continuous flow calculation algorithm based on the distributed photovoltaic properties. The variation law of power grid network loss of the distributed photovoltaic grid-connection was obtained. The simulation results can provide a scientific reference for planning and construction of distributed photovoltaic project.
