Inter-Area Power Oscillations Mitigation for Electrical Systems Via Novel Fuzzy Control Based Braking Resistor Model

Abstract

Power system oscillations jeopardize the secure operation and the integrity of electrical power systems. The main aim of this work is to mitigate inter-area power oscillations motivated by the fact that many catastrophic worldwide blackouts were due to unstable inter-area oscillations. This study should explore dual fuzzy logic controllers to orchestrate a coordinated switching strategy for dual novel dynamic braking resistor models for mitigation of inter-area power oscillations in Kundur’s two-area test system. The obtained simulation results establish exhilarating confidence and optimism that the proposed scheme will effectively mitigate inter-area power oscillations in accordance with a wide perturbation spectrum.
