| 摘 要： | 采用基于遗传算法的综合负荷模型主导参数辨识方法，分析辨识了放射状、弱互联以及其他几种特殊电网组合形态的主导负荷参数。通过对比原始负荷模型与辨识负荷模型的动态仿真曲线，分析了综合负荷模型对电网负荷群外特性的拟合度及适用范围。仿真表明，当负荷区域中没有发电机时单一综合负荷模型可以近似等效其外特性否则，拟合效果不理想。

| Abstract: | With dominant parameter identification method based on genetic algorithm,dominant parameters of the models for different composite loads with different grid connection, such as radial-pattern distributed, weekly connected,as well as several special cases,are analyzed.By comparing dynamic response of original load models and identified models,the feasibility and applicability of using a single composite load model to simulate an area of loads are analyzed.Many simulation cases show that the external characteristic of composite loads can be simulated by a single equivalent load model when there are no generators in the area, otherwise the fitting effect is not ideal. |

| Keywords: | composite load model identification equivalent model |
