Wind power penetration affects the dynamics and operational performance of a conventional power system. This article investigates the stability issues of a power system with the penetration of wind power from a doubly fed induction generator and direct drive synchronous generator. An approach to utilize an existing shunt flexible AC transmission system controller, static VAR compensator, for enhancing the small signal stability of a wind connected power system is discussed here. Supplementary stabilizing control for damping oscillatory modes is applied to static VAR compensator and suitable control input has been selected for the best damping performance of the proposed controller.
