Why is wind energy wasted during the frequency regulation process?
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.
Why is frequency regulation required for wind power plants (WPPs)?
The system inertia is gradually decreasing and frequency security issues are becoming more prominent with the increasing penetration of wind power. To ensure the safety and stability of power system, many countries have updated their grid codes to reinforce the frequency regulation requirements (FRRs) for wind power plants (WPPs).
How DFIG based-wind turbines regulate frequency?
The frequency of the power system depends on the balance between the power generation on the power generation side, and the load on the power consumption side. As shown in Figure 1, the coordinated control system is designed for the DFIG based-wind turbine to implement short-term frequency regulation.
What is the frequency regulation capability of a wind turbine?
The frequency regulation capability provided by wind turbines is limited by the mechanical characteristics and the capacity of the generator set, for which insufficient frequency regulation capability needs to be supplemented by energy storage. The frequency response characteristics of the system are as described in Equation (32)
Can wind power and energy storage improve frequency regulation?
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.
Does wind power participate in frequency regulation?
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.
