基于尖峰电价的家庭能量管理最优控制算法

Control method based on critical peak pricing of home energy management system

智能电网技术的不断发展,为家庭能量管理系统(HEMS)提供了新的研究方向。针对HEMS,提出了一种基于尖峰电价的家庭用电设备最优控制算法,该方法使用层次分析法(AHP)对可调整用电设备的综合满意度进行评估,建立以满意度最高和满意度与费用兼顾为目标的数学模型,同时考虑家庭分布式电源及储能设备对家庭用电的影响,帮助用户满足电力公司在需求响应时段的约束条件的同时,获取最满意、舒适的控制策略。最后通过案例仿真验证所提出的控制算法的实用性和有效性。

The development of smart grid technology provided a new direction for home energy management system （HEMS）. In the view of the HEMS, this paper proposed an optimal control strategy for home appliance based on critical peak pricing （CPP）. This method used the analytic hierarchy process （AHP） to evaluate the comfort level of the adjustable home appliance. Establishing mathematical model with highest comfort level and both highest comfort level with minimum cost, at the same time considered the influence of family distributed power and the energy storage equipment, made the household getting the satisfied and comfortable control strategy. Finally an example proves the practicability and effectiveness of the proposed control strategy.
