Abstract
Generally, the output characteristics of the energy apparatus are nonlinear. Furthermore, because multiple power sources are used in microgrids, many variables must be considered to optimize the system. Orthogonal tables are employed in this paper to reduce the complexity of the problem to plan the optimal operation method of a compound energy system. Therefore, orthogonal table used to experimental design are employed in this presentation to reduce the complexity of the problem to plan the optimal operation method of a compound energy system. The initial values of design parameters of the system near the optimum operation method are determined using result of orthogonal table experiment and the factor effect diagram. Next, the optimal solution is obtained by introducing this result as initial values of GA. The proposed analysis method is available for improvement of the analysis precision by the increase of the number of gene models and the increase of the design parameters. Therefore, proposed analyzing method was overcame weak points of the optimal calculation of conventional simple GA.
