Abstract

Power System Stability is a major domain of renewed interest for electrical power system researchers worldwide. Among the different stability classification domains, large disturbance rotor angle (transient) stability studies are of high concern due to the decommissioning of conventional power plants which leads to a dramatic decrease of inertia and shortcircuit capacity. In this paper, the superiority of a proposed Supplementary Damping Control (SDC) scheme, concerning with transient stability enhancement, is demonstrated against other existing controls, namely, a common form of low-voltage ride through (LVRT) controller with a post-fault ramp, and Voltage Dependent Active Power Injection (VDAPI) control strategy. Based on the analysis done with the modified IEEE 9 bus system with 52% and 75 % share of wind generation, it has been found that proposed SDC has quick damping of oscillations, and also causes a higher reduction of the magnitude of the first rotor angle swing, and has lesser impact on the overall system frequency performance. The controllers’ performance against rotor angle stability threats is tested via EMT modelling and simulation with RSCAD software, which is a real-time digital simulation (RTDS) platform.
