Abstract:The operation scheduling of electrical equipment of the Household Energy Management System (HEMS) under multi-user shared battery is introduced, so the electricity cost can be reduced. Firstly, the flexible load and energy storage equipment in the household are modeled. The goal is to minimize the electricity consumption cost of the home equipment operation scheduling model, so an economical target optimization model is established. The mathematical modeling process takes into account the effects of photovoltaic (PV) power generation and energy storage equipment and allows the sale of surplus power to large power grids. Each user of the cell first calculates its own independent daily electricity cost, and then calculates the cost of the next day for multi-user sharing. Finally, the cost of the optimized scheduling results are compared by simulation, verifying the correctness and economy of the proposed method.
