Transient Stability Study in Grid Integrated Wind Farm

摘要

Transient stability, which is an important aspect in maintaining power system operation, was the focus of this research. Critical clearing time calculation, popular for assesing the transient stability by observing the generator rotor angle performance, was utilized as the assesment method. Wind turbine effect in transient stability is added as the specific problem representing the current condition in Indonesian power system. Three study cases were observed, namely observing the effect of wind farm integration, observing the effect of thermal generator loading, and observing the effect of wind farm penetration level on transient stability. The research is conducted in modified IEEE 9 Bus system with wind turbine modeled as doubly fed induction generator using DIgSILENT 15.1 environment. The result showed that the effect o wind farm integration and the greater the loading of a thermal generator in the system worsen the transient stability performance. Increasing the penetration level of the wind farm in the system also worsen the system transient stability even if the energy cost is zero.
