Inter-area oscillation damping and primary frequency control of the New York state power grid with multi-functional multi-band power system stabilizers

The paper discusses the impacts of the advanced closed loop control through multi-functional multi-band power system stabilizers on dynamic performance of the New York State power grid. Reference signal modulation of certain devices in the system has been shown to improve system damping and affect frequency response during generator outage scenarios. The methodology behind the development of system models and subsequent tuning of the controllers is discussed. Results demonstrate how feedback control of various power system equipment, including those that are electronically-interfaced, can aid in improving dynamic behavior of large interconnected systems.
