基于电力路由器的家庭能量管理系统

Home Energy Management System Based on Electric Power Router

随着住宅区的能源消耗不断增加,为节省能源成本,屋顶光伏和小型风机等分布式能源逐渐引入住宅区。由于目前分布式能源的利用率低,且缺乏有效的能源管理装置,提出一种基于电力路由器的家庭能量管理系统。本系统的核心是具有即插即用和电源转换功能的电力路由器,因其配有交、直流母线,系统内的各种电源可实现联合供电。通过有效的能源调度策略,可根据家用电器的优先级进行负荷调度,以降低用电成本。搭建了硬件试验平台,试验结果表明,电力路由器可实现运行模式的无缝切换,相应的负荷调度策略可提高分布式能源的利用率,降低市电消耗量,保障系统运行的经济性和稳定性。

As the energy consumption in residential areas keeps growing,distributed generations(DGs)such as roof-top photovoltaic and small wind turbines are gradually implemented in residential areas in order to reduce energy costs.Due to the inefficiency in DG utilizations and the lack of effective energy management devices at present,a home energy management system based on electric power router is proposed,whose core is an electric power router with functions of plug-and-play and power conversion.It is equipped with AC and DC buses,so various power sources within the system can provide energy in coordination.Under an efficient energy scheduling strategy,this system enables load scheduling according to the priorities of household appliances,thus reducing the total electricity cost.A hardware experimental platform was set up,and experimental results show that the electric power router can realize seamless switching between different operating modes.The corresponding load scheduling strategy can improve the utilization of DGs,reduce the utility power consumption,and guarantee the economy and stability of system operation.
