Frequency support provided by wind turbine generator (WTG) is important for frequency security of the power system with high proportion of wind power. A WTG initially operating at the optimal point and utilizing rotor kinetic energy for frequency support can only provide temporary frequency support, and avoiding second frequency

A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is
