Control Strategy Research Of Home Energy Management System Based On Energy Router

Home area networks(HAN)will become an essential part of energy Internet in the aspect of energy saving,demand side management and improving the stability of distribution network in the future.The energy router is a better choice to solve the multi-functional energy interface between the HAN and the power grid.In this thesis,a home energy management system based on energy router are analyzed and designed,and a control strategy based on fuzzy logic control for its self-energy storage module are designed.The main work of this thesis as followings:(1)In order to enable the HEMS to make full use of renewable energy sources(RESs),the structure of the home energy management system based on energy router is analyzed and designed.Corresponding mathematical models and their respective control strategies are established for each part of the system.(2)This thesis mainly studies the charge and discharge control strategies of self-energy storage modules in energy routers,and a hybrid energy storage control strategy based on fuzzy logic control is designed,as well as the energy router coordination control scheme composed of the hybrid energy storage control strategy,reference voltage and current compensation strategy.(3)The simulation model of a home energy management system based on an energy router is built in MATLAB2016b/Simulink.The simulation mainly focuses on the self-energy storage module in the energy router and the three related behaviors when the system cooperates with the power grid.The simulation results show that this control scheme enables the HEMS to make full use of RESs.Meanwhile,it can maintain the operational stability of the whole system,and cooperate with the power grid to suppress the impact of RESs output fluctuations and load consumption variations.
