Review of Wind Power Grid Integration Technologies

Abstract

With the continuous expansion of renewable energy, window power generator has become an important part of modern power system. However, the characteristics of easy interruption of wind energy and the rules of grid stability bring great difficulties to the operation and grid of wind turbines. This paper summarizes the key technologies of wind power generation systems. The content also includes the basic structure and action mode of wind turbines, and the system features of fixed-speed induction generator (FSIG) and doubly-fed induction generator (DFIG). We will also learn how to use air force to adjust output, stall control, active stall control and pitch control. In addition, the structure and usage of static var generator (SVG) technology for adjusting reactive power to support voltage are also discussed. In addition, in order to improve the performance and driving reliability when the grid fails, it is necessary to use low-voltage ride-through (LVRT) and high-voltage ride-through (HVRT). Finally, the future development direction and difficulties of connecting wind power to the grid are summarized. This summary introduces the key technologies to improve the efficiency, stability and adaptability of wind power systems.
