HOME / Frequency-divided wind power generation system - CAPTURED ENERGY SOLAR (PTY) LTDFrequency 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.
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.
The frequency response is illustrated by the red-dash line in Figure 12A. The minimum and maximum values of the frequency are 49.69 Hz (point B) and 50.04 Hz, respectively. Case 3: DFIG-based wind power units participate in short-term frequency regulation under the proposed adaptive additive control.
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.
Evaluating the system''s frequency regulation requirements using frequency security constraints and achieving rapid frequency response through coordinated wind-storage control are
