Abstract

Previous transient stability studies investigating the effects of wind power integration into a conventional power system assume the insertion point of the wind-generating units to be at the same bus and interconnection voltage as the synchronous generators they are substituting or complementing. While these assumptions offer some insights into the effects of the wind on the existing system, important points about the physical distance and interconnection voltage of wind farms with respect to the conventional power system are neglected. This paper analyzes the effects of integrating doubly-fed induction wind turbine generators through different transmission line configurations and at different buses. The IEEE 14-bus test system is used in order to compare results with previous works. Results show that connecting wind generators through transmission lines and to different buses introducesdelays in the speed dynamic responses of existing synchronous generators. These delays in turn affect the bus voltage oscillations. Results also show that there is no significant effect on the base cases when using different interconnection voltages to connect the wind. The results of this study can be used by power system operators when deciding how to connect wind farms to an existing power network when optimizing for stability response to a large fault. Overall, wind farms should be connected through additional transmission lines to buses near where synchronous generators are located and further away from loads and higher risk fault areas.
