According to extensive development of renewable resources, such as wind power and photovoltaic power, and on the basis of wind-photovoltaic-energy storage hybrid power system, an optimal scheduling algorithm for residential energy consumption scheduling considering the wind -photovoltaic power and the electricity price of purchase/selling electricity is proposed. Firstly, in order to reduce the electricity cost of user and the burden of power supply, the appliances is arranged in the time-slot

Simulation results show that the proposed optimization can decrease the electricity cost of user and peak-to-average. 26 Copyright ⓒ 2016 SERSC capacity of the combined power generation system is optimized in this paper. It can not only guarantee the stability of the system, but also reduce the system cost [8] [9] [10] [11] . On the basis of wind-photovoltaic-energy storage hybrid power system, an optimal scheduling algorithm for residential energy consumption scheduling considering the wind -photovoltaic power and the electricity price of purchase/selling electricity is proposed. In this paper, taking into account the wind -photovoltaic power and the electricity price of purchase/selling electricity, the household appliances are scheduled. Namely, within the scope of the user's tolerance of the appliance, the appliance is arranged in the time of purchase price is higher than the selling price of electricity and the wind-photovoltaic power is higher periods. And, the coordination strategy of the wind-PV hybrid power generation system is presented : when the power purchase price higher than the selling price, wind-photovoltaic-energy storage hybrid power system is consumed firstly. And in the lack of electricity, the electricity is purchased from the grid; when electricity purchase price is lower than the selling price, users directly purchase electricity from the grid, and the power of wind-photovoltaic system is sold to the grid side. The optimal scheduling scheme proposed in this paper can not only reduce the power consumption of users, but also reduce the power load of the power grid, thus reducing the consumption of fossil energy and reducing the environmental pollution.
