“…The switching dynamics can also be ignored because the PWM frequency in the threelevel VSC NPC is much larger than the system frequency [23]. Therefore, the model of VSC NPC was developed based on (16). where u dqr ,u dqg and m dqr ,m dqg are converter-injected voltages and modulated signals respectively in the rotor and grid-side converters.…”

Wind power technology is the fastest-growing technology for electrical energy production due to its potential characteristics. However, due to its randomness, it has an unnecessary impact on the operation and stability of the grid system. For example, the problem of power grid frequency fluctuation is more obvious. Fluctuations in frequency, in turn, can even affect the breakdown of power systems. To minimize these problems, a droop vector control strategy applied to variable-speed pumped storage (VSPS) systems can be implemented. This method should be used as a wind power fluctuation compensation solution in the wind farm grid-connected system. This chapter introduces the droop-fed direct power control strategy in a VSPS-wind farm-grid-connected system. The modeling of the system is based on the phasor model technique. The spectrum analysis method is used in the VSPS system to determine the dynamic performance of the power grid under wind power fluctuation compensation and emergencies and is verified on the MATLAB/Simulink platform. The results show that the spectrum analysis method is effective for determining the fluctuation and stability requirements of wind power in large power grids. The VSPS control strategy in the wind farm grid-connected integrated system achieves good power flow regulation and stable grid frequency, and the deviation is within an acceptable range.

“…It has been presented and validated that the operating characteristics qualify the performances and dynamic responses of the developed control system when contingencies and faults occur in an electric power system in electromagnetism transient programs [1–11, 14, 17, 20–28, 33, 36, 38–41]. On the other hand, phasor model simulation is quite important to study electromechanical transient behaviours in large‐scale power systems as the VSPS grid‐integrated system are large likewise in which the simulation time is critical, the computing is vital and the difficulty of small insight quantities for control and protection designs occurs [10, 42–44]. Hence, phasor model simulation is reasonably significant for such solutions.…”

“…e active power is controlled by adjusting the rotor speed especially during the pumping mode [19][20][21]. A doubly fed induction machinebased variable-speed pumped storage (VSPS) system was established to investigate the performances in generating mode based on a comparison of phasor model and detailed model simulations [22]. e reactive/active power responses in a very short time for voltage and frequency control enables more dynamic tracking of the load variation because the power of the pump-turbine is proportional to the third power of the unit speed [21,23,24].…”

The integration of variable-speed pumped storage unit (VS-PSU) guarantees an efficient peak regulation and frequency modulation of the power grid. The present research analyzes the active power flow of the VS-PSU under synchronous, subsynchronous, and supersynchronous speed in both generation and pumping modes. The control strategy of the VS-PSU is realized by the dq-axis vector control method. Furthermore, the control of the VS-PSU integrated with wind power has been conducted using DIgSILENT platform with the VS-PSU of 300 kW capacity. Results show that the fluctuation of the power output of the wind power plant can be reduced effectively. The safe, economical, and stable operation of power system integrated with wind power can be achieved by the significant contribution of the VS-PSU.
