微电网中含有规模化灵活可控的柔性元件，采用传统配电网等值方法进行微电网等值会带来一定的不适应性。为此采用电力系统负荷建模中的总体测辨法研究微电网的等值模型，在考虑微电网控制策略对其外特性影响的基础上提出合理的模型结构，并用免疫算法对模型参数进行辨识，所提出的模型为非机理模型，能较好地还原微电网的动态特性。最后，通过故障仿真校验的方式验证了模型的有效性。

As the microgrid contains large-scale flexible components,adoption of the traditional distribution network equivalent method for microgrid equivalence will bring about definite inadaptability to microgrid equivalent research.For this reason,the overall measuring and identification method is employed to investigate the equivalent model of microgrid,and a rational model structure considering the influence of the control strategy on the external characteristics of microgrid is presented.The parameters identification of the model is solved by the immunity algorithm.The proposed model is a non-mechanism model capable of better restoring the dynamic characteristics of microgrid.Finally,the effectiveness of the model is demonstrated via fault simulation.
