Optimal Power Consumption Management in a Smart Building in Presence of PHEV, Storage Battery and PV Panel

Abstract

Energy management programs lead to significant residential electricity billing decline at the customer level and improve the operating condition of the power system at the higher level. In this paper with the goal of energy management, the smart building loads in presence of plug-in hybrid electric vehicle, storage battery and PV panel system, are categorized in two groups as controllable loads and un-controllable loads. With considering the consumer welfare, the optimal smart home dispatch is done with aim of minimizing the electricity billing using the mixed integer linear programming method. To this end, first, the operational behavior of each load and other smart home facilities are mathematically modeled and considered as constrains of the optimization problem. Then, the cost of electricity consumption is modeled based on the hourly electricity tariff and is used as the objective function to be minimized. The proposed model is simulated in GAMS and the optimal dispatching schedule is presented in some scenarios. The results show the significant cost decline, load shifting and peak shaving.
