摘要：

According to the distributed consensus theory, a distributed optimization control method is proposed for DC Microgrid to optimize its power distribution. Specifically, the optimal solution of economic dispatch problem (EDP) is obtained by the consensus of incremental costs, and the power generation limits of distributed generators (DGs) are considered. Furthermore, a load observer is introduced to avoid power distribution errors caused by the line resistances in each DG. In order to enable the microgrid to operate at the optimal operating point obtained from the upper control layer, an improved distributed cooperative controller is designed. The simulation results based on MATLAB/Simulink illustrate the effectiveness and time-varying adaptability of the algorithm, even if the demand changes or the power generation limits of some generators change.
