Series capacitor combined with power system stabilizer for enhancement of power-systems voltage synchronous stability

The paper presents a nonlinear dynamic controller for a combination of static series capacitor compensation and power system stabilizer, for enhancement of both voltage and transient stability of power system. The proposed controller implements speed deviation signal and generator terminal current deviation signal. The proposed scheme is validated using a sample single machine infinite bus power system loaded by a frequency dependent voltage dependent nonlinear dynamic load type.
