This article first introduces the structure and principle of two mainstream wind turbine models, analyses the different power generation principles and energy transfer structures of these two different wind turbines, and briefly introduces the network topology structure of wind power stations, as well as the direction of command data from the control end to the controlled end. Then, it introduces and analyses several widely used maximum power point tracking (MPPT) control algorithms and frequency control methods, summarizes and predicts these algorithms for single wind turbines, and lays the foundation for future research. Large-scale wind power and other new energy grid connection is one of the most effective solutions to address the world energy crisis. With continuous development of technology, more and more power electronic control components are being closely integrated with traditional power systems, and we are facing problems different from those in the past. We must change our thinking and work hard to address these issues.
