Research On Energy Management System For Optical Storage And AC/DC Microgrid

With the development of economy,energy demand in many countries has caused energy shortage,and the combustion and emission of traditional fossil energy has also caused environmental pollution.Thus,in recent years,new energy technologies such as optical storage and charging have begun to develop rapidly,but a single renewable energy structure will destroy the stability of the grid.AC/DC micro-grid is adopted to provide the main power supply through the pv system,frequency and peak regulation through the energy storage system,and then the strategy of energy management system is adopted to supply the load.In this paper,the energy management of AC/DC microgrid is studied.In this paper,a set of experimental system design of optical storage charging AC/DC microgrid is proposed,and an AC/DC hybrid microgrid with photovoltaic power supply system,energy storage and storage system,charging piles and other loads as energy consumption system is constructed.In the design and control of photovoltaic system,the maximum power point tracking is realized through the simulation and Simulation of photovoltaic system.In the design and control of energy storage system,according to the existing mainstream energy storage equipment,the energy storage system suitable for photovoltaic system is selected,and the general model is selected as the research object.According to the characteristics of energy storage container,the heat dissipation of container is simulated to ensure the normal of the whole system.For charging piles,the characteristics of existing charging piles are analyzed,the topology structure is drawn,its functions are improved,and relevant interactive operation interfaces are set up.Finally,based on the characteristics of photovoltaic power generation and the economy of energy storage system,a coordinated control strategy is proposed for the whole energy management system.According to the time-sharing strategy of peak and valley level in a certain area,the specific structure of the energy management is described in detail,and the topological structure of the system is designed to improve the photovoltaic system.Considering the utilization rate of energy storage system,it has high economic efficiency.The above work has a good reference value for improving the economy of microgrid operation.
