The various characteristics between distributed energy resources, the insufficient network communications and the privacy-preserving demands in microgrids for distributed economic dispatch(DERs)of are challenges.In this paper, we build up the microgrid's distributed dynamic economic dispatch model considering the generation cost of power production by conventional units, the abandoned cost of renewable energies, the storage devices depreciation expense, active power loss expense of the network.And the microgrid model is divided into regions based on the access locations of power supply units and energy storage devices.By using the synchronous alternating direction method of multipliers algorithm, each region only solves its individual optimization and exchanges the phase angle information with its neighbors at each iteration, to realize the optimal solution.We also test a real microgrid to show the accuracy and effectiveness of this algorithm.
