Active and reactive power control of a variable speed pumped storage system

Variable Speed Pump Storage for the Mitigation of SSR in Power System with Wind Generation

“…As many studies [11,12] support this assumption, the aggregation of a wind farm provides a reasonable approximation for system interconnection studies. According to system studies [13][14][15][16], simulations of bulk system dynamics using a single machine equivalent is adequate for most planning studies.…”

“…Equation 5explains that the active power and reactive power are independently controlled. is reveals that RSC o ers a proper AC excitation for the windings of the rotor that provides the stator windings proper active power and used for controlling the turbine output power and the reactive power which is measured at the terminals of the stator of the machine Based on [13], with the implementation of the vector control method, the stator ux is aligned with the d-axis. Taking the stator ux equations in (3), one can deduce that Ψ = 0, and Ψ = Ψ .…”

Modelling and control of doubly fed variable‐speed pumped storage units for grid power regulation

“…Li and Hedman [8] studied conventional pumped storage and VSPS, and showed that the VSPS is more effective than the conventional pumped storage in balancing renewable uncertainties of power systems. Nasir et al [9] established the control model of the VSPS, and proved the feasibility of active and reactive power controls. Bocquel and Janning [10] showed that a doubly fed induction generator (DFIG) of 300 MW has been successfully used in a pumped storage power station in Germany.…”

Research on self‐starting strategy of variable speed pumped storage units based on model predictive control

“…Recently, the researches about VSPSU are mainly focused on its excitation control system, and due to its great similarity with that of the wind power doubly‐fed induction generator (DFIG), the control system has been well developed [5–11]. However, there is great difference between the two in the start‐up processes.…”
