Research on Optimization Method of Home Energy Management System in Smart Grid

In order to save users' electricity costs, this paper proposes an optimized management method for the home energy management system. Firstly, a household power grid is constructed that include photovoltaic system, energy storage system, power adjustable load, unscheduled load, and time adjustable load model. Secondly, in order to obtain a solution that can both rationalize the allocation of household load working time and minimize household electricity costs, a double objective function is defined. Considering the real-time price of the power grid, the optimization strategy for household energy management is formulated. Finally, simulating the daily electricity consumption of households to verify that the optimized management method of the household energy management system can effectively reduce users' electricity costs.
