Wind Power Generation

Wind power generation is the most widely used way to use wind energy in modern times. Wind power generation systems have shorter set-up time and can work continuously if the wind speed is enough [31–33] g. 5 is the typical framework of a wind power generation system. For a wind power generation system, the wind turbine is a critical part.
