Frequency characteristics comparisons of frequency regulation methods. It was found that wind power participation in frequency regulation provides inertial response and frequency regulation standby capacity, which causes the lowest point of system frequency response under disturbance elevated and steady-state frequency deviation to be reduced.
Results from [ 7] show that some wind energy is wasted during the frequency regulation process because the wind turbine can only use the energy stored in the rotor. Energy storage systems are applied to wind farms to help maintain the frequency stability of the system after wind power is connected to the power system.
With the developmental f wind turbine technology, wind turbines can participate in the frequency regulation of the grid. Reference [ 3] proposed an integrated inertia support method based on doubly fed asynchronous wind turbines, which supplement the rotating power of low-inertia power systems.
The participation of wind power and energy storage in frequency regulation can significantly improve the amplitude-frequency response gain of the power system. Wind power and energy storage can significantly suppress the disturbance gain in the frequency band below the fundamental frequency.
