Active Distribution Networks with Microgrid and Distributed Energy Resources Optimization Using Hierarchical Model

Distribution networks have undergone a series of changes, with the insertion distributed energy resources, such as generation, storage systems, and demand response, allowing consumers to produce an active role in distribution systems. Thus, it is possible form microgrids. From grid’s point view, necessary plan operation considering resources microgrids connected it, aiming ensure maintenance grid economy operational safety. So, this paper presents proposition hierarchical model for planning daily grids In case, entire optimized results from microgrid optimization itself. If none technical constraints, example voltage levels, are reached, optimized, however, if there some violations constraints feedback sent internal be run again. Several scenarios evaluated verify iteration among controls coordinated way microgrids, well network. A specifically when they allocated operated way, reduction operating costs, losses, greater flexibility security whole system.
