Bibliography:This paper describes the emergence background of the concept of micro grid, current status and the overall framework of Henan micro-grid demonstration system of State Grid Corporation. Micro-grid system controller connects large grid with the micro grid and controls them in this pilot project, achieving the smooth transition from grid-connected to off-grid and from off-grid to grid-connected with the corresponding secondary equipment. The device mainly completed the following functions including island detection, automatic synchronization parallel and protection and monitoring functions. This paper summarizes the implementation principle of the device and related criteria. Finally, based on the results of the project, the focus and difficulties of the future research are proposed.
