Microgrid (MG) contains large scales of flexible components, so the traditional distribution network equivalent method is not applicable in MG equivalent research. In this study, a novel MG model structure considering the influence of control strategy on the external characteristics of MG is presented, in order to make measurement‐based modelling approach more suitable for equivalent research of MG. The proposed model is a non‐mechanism model which can restore the dynamic characteristics of MG better, and the parameters identification of the model is solved by improved immune algorithm. Finally, through the fault validation way the effectiveness of the model is demonstrated.
