Robust Economic Dispatch of Grid-connected AC/DC Hybrid Microgrids

Considering the uncertainties from renewable energy sources and loads, the paper presents a novel two-stage robust optimal economic dispatch model for grid-connected AC/DC hybrid microgrids. The model is decomposed into a master and slave min-max-min problem with mixed integer linear structure. A robust economic dispatch result is obtained by using the column-and-constraint generation algorithm(C&CG) to solve the day-ahead optimization problem for AC/DC hybrid microgrids, which minimizes the daily operating cost. A case study is conducted to further demonstrate the effectiveness and capability of the proposed model in this paper for the operation dispatching of AC/DC hybrid microgrids.
