As shown in Figure 5, the highest and lowest electrical production of renewable energy system is related to September and December months. For September electrical production is 91 KW/day and this amount for December is 50KW/day. For September, the amount of production by wind turbine and PV cell is 81 and 10KW/day, respectively. While for December, the amount of electricity produced by wind turbines and PV cell is 30 and 22KW/day, respectively.
The problem is solved as multi-objective, and the results show that the system parameters have been improved in multi-objective mode. The following tables show the parameters used for simulation.
