Abstract: The gradual increase of the penetration rate of new energy connected to the grid leads to the reduction of inertia and damping of the grid, which consequently diminishes the stability of the power system. In response to the above problems, this paper proposed an active support grid-connected power generation system based on new energy and permanent generator-motor pairs. Firstly, the basic power generation principle of the motor was introduced, and the damping characteristics of the system were analysed. Then, the multi-mode control method of the system was introduced, including permanent magnet synchronous motor control and grid connection control. The experimental results of the system in actual photovoltaic stations show that this system has functions such as green power generation, frequency support, voltage support and reactive power regulation, which can improve the stability of new energy power generation systems.
