Review on Multi-objective Joint Economic Dispatching of Microgrid in Power System

As the global energy crisis and environmental pollution problems are becoming more and more serious, the microgrid (MG), as an effective supplementary means of large power grid, has gradually become the focus of attention. With the gradual maturity of MG technology and deepen practice of engineering application, the economic dispatching of MG has become the key issue in the field of MGs. This paper analyzes the status quo of domestic and international researches on MG economic dispatch from multiple perspectives, such as dynamic and static economic dispatch, demand side response, energy management and multi-MGs joint dispatch. It points out that the economic dispatching of micro-grid still has some problems to be further studied. For instance, the imperfect of uncertainty researches on renewable energy (RE) and load demand (LD) and the immaturity of research on MG economic dispatch. Finally, a summary and prospect for economic dispatch research is concluded.
