Impact of DFIG based wind turbine generators on transient and small signal stability of power systems

Effect of wind penetration on power system stability

“…However, [10], [11] present results which show both positive and negative impact due to wind penetration. A study system with 22000 buses is used in [10]. [12] presents impact of wind integration in Norway on damping of inter-area oscillations in the Nordic grid.…”

Towards a wind farm reduced-order model

“…One of the main concerns is whether with a high wind power penetration the system is more prone to instability due to a relative reduction of the system inertia. Small signal stability has been used to study this hypothetical problem [17]. The basis of this study is to replace WTGs with equivalent SGs and, through sensitivity analysis with respect to the equivalent SG inertia, identify which modes are affected in a beneficial or detrimental way.…”
