This thesis investigates the stability effects of the integration of wind power on multi-machine power systems. First, the small-signal stability effects of turbine governors connected to synchronous generators in the presence of large-scale penetration of wind and load power disturbances are analyzed. Results suggest that tuning the turbine governors when wind power generation is present can improve the small-signal stability of an interconnected system. Then, the transient stability effects of integrating doubly-fed induction wind turbine generators through different transmission line configurations and at different buses are analyzed. Results show that connecting the wind through transmission lines and to different buses introduces a delay in the oscillatory response of the synchronous generator speed, and bus voltage oscillations are also affected. Results also show that there is no significant effect on the base cases when using different interconnection voltages to connect the wind. Overall, the results can be used by power system operators when making decisions on turbine governor tuning and transmission line configurations when connecting wind farms to existing power systems while optimizing for small-signal and transient stability response.
