Study On Economic Operation Optimization Of Microgrid

As an effective supplement of the great power grid and an effective form used by the distributed energy, microgrid has attracted wide attention from scholars of various countries. With the development of the research on microgrid, economic uncertainty will become an important factor that obstacle the improvement of microgrid. So it is urgent to study the economic operations of microgrid in-depth. Based on the analysis of the structure of microgrid, energy management systems and economic operated strategy,in this paper, an optimization model of economic operated microgrid system containing CCHP is established. By intergrating these problems, such as the scheduling of generators, intelligent management of energy storage units and optimization of operated efficiency of the network, into a uniform optimization problem, the complexity of application optimization algorithm is reduced. Finally, two examples are given respectively under the two modes of operation. The optimal combination of generators and the best energy trading scheme are presented in this paper. The effectiveness and feasibility of the economic operated strategy are also overall demonstrated.
