Impact on Transient Angle Stability with DFIG-Based Wind Generation Connected to Power System

Abstract:

This paper investigates the impact of wind generation consisting of doubly-fed induction generators (DFIG) on the system angle stability. 3 different factors are considered: the penetration level of wind generation, the connection location of wind generation and the reactive power control strategy that the DFIG utilizes. A modified IEEE-3 machine and 10 bus system has been used as the test network and a number of simulations have been conducted. It shows that the higher the penetration level of the DFIG-based wind generation, the better the system angle stability. Compared with unity power factor control strategy, the system stability is better when the DFIG utilizes constant voltage control strategy. Beside, different connection locations of wind generation also have effects on system stability.
