The impact of large scale wind power generation on power system oscillations

Small-signal stability of wind power system with full-load converter interfaced wind turbines

“…Also, the presence of non-synchronous generation units reportedly can have an impact on the damping of interarea oscillations. In [11]- [13] comparisons are presented of the influence on power system oscillations of WPPs based on fixed-speed induction generators (FSIG) and doubly fed induction generators (DFIG). In the studies it is generally found that FSIG WTs increase the damping of the power oscillations.…”

“…In the studies it is generally found that FSIG WTs increase the damping of the power oscillations. References [11], [13] also report increased damping from the DFIG machine while [12] notes that the DFIG does not have any significant effect on the damping.…”

Small-Signal Stability Effects of Wind Power Integration Capacity and Accommodation on Interconnected Power Systems

“…In recent years, many research efforts have been devoted to the development of stability of power system with wind power integration [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The impact of the damping characteristic of power grid with wind turbines interconnected was firstly proposed by JG.…”

Transient Stability Improvement of a FSIG Based Grid Connected wind Farm with the help of a SVC and aSTATCOM: A Comparison

“…With the increase in the ratio of wind generation to conventional generation, several problems related with integration of wind farms have emerged. These problems are due to distinct properties of the generators used with the conventional form (Thermal & Hydro) of generation and wind based generation [1]- [4]. In thermal and hydro power based generation synchronous generators are used while in wind based generation mostly induction generators are used.…”

“…This problem is mainly due to the existence weak transmission grids in the rural areas [1]- [4]. Earlier when the Manuscript share of wind power generation as compared with the conventional generation was low, during transient conditions; whenever the power system reached on the verge of instability the wind farm was disconnected from the grid and was reconnected when transients passed away.…”
