With the large increase of load users，the load side adjustable resources gradually increase，and the load side demand response（DR） resources are used to participate in microgrid scheduling to improve the level of new energy consumption. In order to give full play to the scheduling potential of DR resources and optimize the user side load management capability， a multi-time scale optimal scheduling strategy for microgrids that takes into account scheduling priorities was proposed. Firstly，according to the response characteristics of different DR resources，the price-based demand response（PDR） resources and incentive-based demand response（IDR） resources were subdivided into five types，and a DR model was constructed to match the scheduling period. Secondly，the multi-times cale optimal scheduling model of "day-intra-day 1 h-intra-day 15 min" was constructed，optimized scheduling of various adjustable resources in the microgrid，and established priority weights for real-time adjustable resources that have a direct impact on users' electricity consumption behavior. Finally，taking an actual microgrid as an example in Fujian，the simulation verifies the validity of the model.
