6 FAQs about Wind power generation for system frequency regulation
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.
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.
Can wind power and energy storage participate in frequency regulation?
Currently, research on the control of wind power and energy storage to participate in frequency regulation and configuration of the energy storage capacity is at its nascent stage. Similar to wind generators, energy storage can be involved in system frequency regulation through additional differential-droop control.
Can wind turbines participate in the frequency regulation of the grid?
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.
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)
How can wind turbines and energy storage devices improve system frequency stability?
In the power systems with high proportion of renewable power generation, wind turbines and energy storage devices can use their stored energy to provide inertia response and participate in primary frequency regulation for the improved system frequency stability.
