Abstract

In the era of smart grids, wireless communication technology improves the flexibility of data transmission for home appliances. Home energy management systems facilitate the maintenance and updates of hardware in the home while coordinating the direction of energy flow between photovoltaic (PV) storage and energy storage, and their various loads. This study designs an energy management system for PV and energy storage devices of ordinary household users to achieve optimal economic energy dispatching within the household and energy trading between the household and the power grid. Considering the network communication between home devices, this study establishes the Zigbee network by hardware devices to realize the data transmission link of the energy management system. Communication interference experiments with communication data loss that occur at different times are designed to study the influence of water wave effect on the economic operation of users’ home load. Experimental results show that when the positive difference between the PV power generation and load is larger, communication failure occurs, and users bear a higher operation cost.
