基于多用户共享的家庭能源管理系统

Multiuser Based on Share Cost-effective and Comfort-aware Electricity Scheduling for Household Energy Management System

多用户共享蓄电池下家庭能源管理系统(HEMS)的电气设备运行调度,可以使电费减少。首先,对家庭中柔性负荷和储能设备进行建模,目的是使得家庭设备运行调度模型的用电费用最小,建立具有经济性的目标优化模型。数学建模的过程中考虑了光伏(PV)发电和储能设备的影响,并允许向大电网出售剩余电力。其次,对小区的每一个用户先分别计算各自独立的一天用电费用,再计算多用户共享下的一天费用。最后,通过仿真对比二者优化调度结果的费用,以验证优化方法的正确性和经济性。

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.
