Abstract: The existing scheduling methods of microgrid do not consider the generation characteristics and demand response side of the power supply， resulting in the power of the microgrid after dispatching cannot reach the ideal value. Therefore， a multi-time scale scheduling method of microgrid taking the demand response into account is proposed. In the analysis of the generation characteristics of different distributed power sources in microgrid and the characteristics of different loads on the demand side， the load is classified according to the characteristics of loads. According to load classification results， the overall problem of microgrid is converted into resident residents optimization problems and multiple time scale problems. Taking the minimum power cost and the minimum charge and discharge cycles as the target， constructs a multiple time scale micro power grid scheduling model. The improved firefly algorithm is used to solve the model to obtain the optimal scheduling scheme. The experimental results show that the proposed method can obtain the optimal scheduling scheme.
