Abstract
The site specific impact that a non-utility generator (NUG) can have upon the oscillatory stability of the Taiwan power system is investigated. The transmission network in Taiwan has been experiencing poorly-damped low frequency oscillations since 1984 due to its longitudinal structure. Therefore, it is essential to evaluate the effect of a non-utility generator on the oscillatory stability of the whole network before it is connected to the system. To do this, an NUG impact evaluation procedure is developed to reach an oscillatory stability index (OSI) which can be employed to evaluate the effect of the NUG at a particular site on system stability. The effectiveness of the proposed impact evaluation procedure is demonstrated by a stability analysis of the Taiwan power system with the NUG installed at different locations. It is expected that the proposed method will provide a valuable quantitative index which can be used to explore the adequacy of the transmission facilities in the utility when an NUG is ins tailed at a specific site.
