| Abstract: | In this paper, an optimization model of the economical operation of the microgrid system containing CCHP is established. With the requirements for environment protection considered, the advanced GE Algorithm is used for simulation and calculation of the model of the island microgrid. Based on an analysis of a specific microgrid case containing many types of microsources, a concrete economical operation plan is given for the microgrid operated as an island. The results prove that the model and GE Algorithm are correct and effective for analyzing the economical operation characteristics of the island microgrid, and the results also suggest that the optimized scheduling of the storage batteries can reduce the overall operation cost of the microgrid system. |
