在城网改造中，基于不同类型负荷的特性进行负荷优化组合，可以提高电力设备利用率和降低配电成本。基于不同类型负荷的典型日负荷曲线，建立负荷优化组合模型，进而建立变电站综合负荷优化模型及馈线综合负荷优化模型，通过调整变电站或馈线负荷中某类负荷的供电来源，对不同类型负荷进行优化组合，改变供电的综合负荷特性，提高了配电网整体效益。通过在广东某地区局部配电网改造中的应用，说明研究工作的有效性。

In the renovation of the urban power network, the utilization of electrical equipment can be improved and distribution costs be reduced through the optimal combination of different types of loads. An optimization model of the substation and feeder composite load is built based on the typical daily load curves of different types of load. The model can optimize characteristics of the composite load to improve the overall efficiency of the distribution network by adjusting the power source of a certain type of load in the composite load. The effectiveness of the study is verified by its application in a local distribution network renovation in Shanghai.
