Energy Management System Of Residential Microgrid Based On Energy Router

With the increasing global energy shortage and environmental pollution,distributed renewable energy has become the focus of social development.Under the premise of the growing distributed power and smart grid,smart home micro grid energy management system,as the agent terminal of smart grid distributed in each family,is bound to be vigorously promoted.This paper takes the development and consumption of renewable energy as the research background,and takes the home energy management system as the research object,designs a residential micro grid energy management system based on the power router,including the system topology and optimal control strategy.Among them,the power router plays a very important role.It not only connects to distributed power equipment,municipal power and various household loads,but also manages and controls these equipment independently to achieve the desired optimization goal of users,which has a real sense of "autonomous operation".In terms of control strategy,aiming at the strong randomness of renewable energy power generation and household load,as well as the complex energy scheduling problem caused by the flexible charge and discharge of energy storage battery,the fuzzy control algorithm and the improved discrete binary particle swarm optimization algorithm are used to carry out multiobjective optimization of the system model,and the operation state of the system in each period is obtained under the constraints of different characteristics,the work state of schedulable load and the charge and discharge power of battery and electric vehicle are designed to achieve the coordination of source,storage and load in the household energy management system,so as to achieve the purpose of scientific power consumption and enhancing the adaptability of the system.Considering the topological structure and design purpose of the system,the hardware and software structure of the power router is designed and the experimental platform is successfully built for system test.The experimental results show that the power router can realize the seamless switching between power supply and load and the free switching of each operation mode;it can successfully realize the interconnection function of the system microgrid and has good transient stability;it can achieve the goal of energy saving and peak staggering through the optimized load scheduling of the system,and keep the user satisfaction at a high level;it can reduce the photovoltaic feed as much as possible At the same time,the influence of the grid on the grid ensures the local absorption rate of photovoltaic and the reliability of users’ power consumption.Finally,the designed system realizes the residential energy autonomous management,improves the comprehensive income of users,and has an excellent application prospect.
