The invention provides a micro grid energy optimization control and management system based on the Internet technology. The system is characterized in that each micro grid and a large grid are connected through an isolation switch and an isolation transformer, and the connection with and isolation from the large grid are realized through the switch-on and switch-off of the isolation switch. At the same time, adjacent micro grids carry out electric energy mutual supplement through a two-direction switch. A scheduling control client accesses a background management server through a VPN. The micro grids and the two-direction switch communicate through the VPN and the background management server. According to the invention, the Internet technology is used, the backup and data analysis of each micro grid are carried out at a cloud end such that the coordination between the large grid and the micro grids and between the micro grids is improved, the technical problem of three-phase load unbalance is solved fundamentally by using the load commutation technology, and thus the micro grids can operate more healthily and efficiently.
Description
technical field [0001] The invention belongs to the field of smart grids, and in particular relates to an Internet technology-based micro-grid energy optimization regulation and management system. Background technique [0002] With the continuous development of the power system, more and more micro-grids are connected to the system, such as small solar power stations, biomass power generation, wind power and other new energy systems. At present, the microgrid generally adopts the master-slave control method, which is independently connected to the large grid and can realize grid-connected operation and off-grid operation. However, this only realizes the connection between the microgrid and the large grid. At the same time, the cloud control of the micro-grid cannot be realized to fully utilize the energy of each micro-grid. The capacity of the microgrid is relatively small, and the ability to resist risks is small. During operation, the three current imbalances caused by th...
