Contact UsIn view of the above problems, a control strategy of wind and storage participating in the primary frequency regulation of the power system is proposed considering the energy storage recovery strategy.
In the first strategy, both wind turbines and energy storage do not participate in frequency regulation. The second strategy is that the wind turbine adopts variable coefficient control. The third strategy is that both the wind turbine and the energy storage system are controlled with constant coefficients.
Wind and storage joint primary frequency regulation control strategy Based on the above analysis of the virtual inertia and battery droop control of the DFIG, this paper proposes a control strategy for the primary frequency regulation of the wind and storage joint participation system. The control block diagram is shown in Fig. 5. Fig. 5.
Then, based on the analysis of the generation mechanism of OPSA and SFD, a combined wind-storage FM control strategy is proposed to improve the system's frequency response characteristics.
Participating in the primary frequency regulation of the system with the energy storage auxiliary wind turbine can further reduce the depth of the system frequency drop and improve the secondary drop of the system frequency.
Wind turbine generally operate in MPPT mode, and the primary frequency regulation capability is realized through additional control, but when the wind turbine uses the kinetic energy of the rotor to participate in the primary frequency regulation of the system, it will cause a secondary drop in the system frequency.
