چکیده مقاله :
In this paper, energy management in a smart residential complex is investigated in both AC and DC modes. The contribution rate of solar and wind generators and the charging and discharging planning of the energy storage system is calculated to supply the load of the residential complex. To analyze the proposed method, a planning problem using three-price electricity tariff is used to show the efficiency of the energy storage system. Voltage converters in AC residential complex are more than DC residential complex. The greater number of converters makes the AC residential complex more complex. A large number of voltage converters and a decrease in efficiency in voltage converters cause more energy losses and higher operating costs. In the simulation part, the amount of required production power and the costs of power production in both AC and DC modes have been calculated. The results presented in this article show that with proper energy management, the DC smart residential complex will have lower operating costs than the AC smart residential complex.
