DYNAMIC STABILIZATION OF POWER SYSTEMS THROUGH REACTIVE POWER MODULATION
Electric Machines & Power Systems, 1986ABSTRACT This paper demonstrates the significant benefits in the dynamic stability improvement of power systems by reactive power modulation in response to a local control signal derived from bus frequency. Static var compensator (SVC) with a thyristor controlled reactor scheme is considered for reactive power modulation. The benefits of reactive power

Dynamic Stability Enhancement of Power System Using Intelligent Power System Stabilizer
2014The destabilizing effect of high gain in voltage regulators persists in power system. The power oscillations of small magnitude and high frequency, which often persisted in power system, present the limitation to the amount of power transmitted within the system. In this paper, a linearized Heffron–Phillips model of a single machine infinite bus (SMIB)
