Possible impact of large scale wind energy integration on small signal stability

The growing concerns of climate change and depletion of fossil fuels are driving rapid development of wind generations. However, the integration of large scale wind generation may compromise the stability of the power system. Besides, the same source of renewable generation such as wind may deploy various technologies such as Doubly Fed Induction Generator (DFIG), Squirrel Cage Induction Generator (SCIG) and Direct Driven Synchronous Generator (DDSG). The generation mix with these wind generators and existing synchronous generators may dynamically interact within themselves or with each other resulting the weak damping or positive damping on the critical modes of low frequency oscillation. This paper aims to explore the same using the simulation results obtained from the DSA Tools®.
