[Abstract]:Microgrid is one of the most effective ways to make use of renewable energy. It is very important to realize the energy management of microgrid and reduce the impact of microgrid on the distribution network. This paper has designed the energy management system based on the switching mechanism of the circuit, which has realized the energy management of the microgrid and reduced the score. The negative impact of cloth power generation on the distribution network, at the same time realize the optimal matching of power and load, and achieve the purpose of full and reasonable utilization of renewable energy. This paper mainly completed the following work: 1. the research significance of the micro grid energy management system and the status of domestic and foreign development are introduced, and the energy pipe based on the switching mechanism of the circuit is also introduced. The operation mode of the system, the control method, the technical standard of the grid operation, the optimized operation measures, and the related technical problems involved are summarized and summarized, and the theoretical foundation for the design of the energy management system based on the switching mechanism of the circuit is laid, and the overall design scheme of the energy management system based on the switching mechanism of the circuit is put forward by.2.. The main components of the energy management system based on the circuit switching mechanism are completed, including the main control module, the AC acquisition module, the DC acquisition module, the switch array module and the corresponding accessory hardware design.3.. The energy management system software is designed based on the switching mechanism of the circuit, and the micro grid energy pipe is put forward. The management strategy of the system has completed the main control program of the power management system of the micro grid, the program of power supply and load matching, the data acquisition program and the data storage program design.4., based on the hardware and software design of the energy management system based on the switching mechanism of the circuit, the experiment of the energy management system based on the switching mechanism of the circuit is built. The platform realizes the smooth switching of the load, the optimization of the power supply and the load, the reasonable adjustment of the energy storage device and the safe and stable operation of the system. The energy management system based on the switching mechanism of the circuit can be combined with the distribution network, and adjusts the power by using its own energy storage device according to the real time power supply of the distribution network. The aim of cutting the peak and filling the valley is to monitor and manage the renewable energy and load effectively, to improve the stability and reliability of the operation of the power grid. It is very suitable for the energy management of the microgrid in the family and the small office.
