Optimization of capacity configuration in island mode micro-grid

To ensure the power supply reliability as well as to improve the profit of the whole micro-gird, in this paper, an optimal design of capacity configuration is presented which could supply the basic power demand. Specifically, the complex cost, which contains the capitalized cost, operating cost and other maintenance cost, is selected as the optimal object to optimize capacity configuration. Then, Genetic Algorithm is adopted to search for the globally optimal solution of the system, and finally the result is compared and inspected in Homer software in which the reasonableness of the proposed model and algorithm is verified.
