Abstract

This paper analyzes the impact on transient and frequency stability for a power system at very high wind penetration (40% wind). Wind penetration is based on the doubly-fed induction generator (DFIG), and a systematic approach has been adopted for wind power integration. A sensitivity analysis has been carried out for each wind integration scenario and for different wind generator loading conditions. A range of fault locations has been selected for stability analysis based on the proximity to synchronous generation and wind farms. The analysis has shown that transient stability performance is subject to fault location in the network, especially when faults are initiated in areas with very high wind penetration. Frequency stability analysis has also shown that areas with lower inertia are more affected by generator outage events than other areas of the interconnected system. The impacts are exacerbated by an increase in wind penetration in the system, and a significant reduction in damping capability has been observed for DFIG-based high wind penetration.
