Aiming at the integrated operational goal of source network load and storage, an active distribution network coordinated operation scheduling method considering source network load and storage is proposed. Based on the idea of multiple timescales, a day ahead day optimal dispatch model of an active distribution network with two complementary timescales is established with the objective of minimizing the adjustable quantity and maximizing the new energy consumption. A differential evolution algorithm and empire competition algorithm are combined to solve the optimal scheduling model. Simulation verifies the superiority of the proposed method. The simulation results show that this method can effectively reduce the load fluctuation and operational cost, increase the new energy consumption rate by 9.1%, and has clear practicality.
