“…Type-2 fuzzy logic becomes preferential choice for many researchers when there are control situations characterized by the difficulty of determining the appropriate membership function for a fuzzy set [19]. Controllers based on Type-2 fuzzy logic theory have been utilized for handling many power system problems as a superior alternative for conventional fuzzy logic controllers [20][21][22][23][24][25][26]. Many works of literature highlights approaches based on the Type-2 fuzzy logic theory to design intelligent power system stabilizers for damping slower type of oscillation [20,23].…”

“…Many works of literature highlights approaches based on the Type-2 fuzzy logic theory to design intelligent power system stabilizers for damping slower type of oscillation [20,23]. Type-2 fuzzy logic is implemented to control a TCSC device to provide supplemental damping to the power system oscillations [24,25]. It is used to design an intelligent control strategy for integrating the doubly fed induction generator (DFIG)-based wind turbines to the distribution network [26].…”

Inter-area oscillations are, by far, the most detrimental oscillation category to the integrity of synchronously interconnected power systems. Inter-area oscillations are characterized by the inherent weak damping. The inherent poor damping associated with the inter-area oscillations leaves open wide probabilities for irrevocable widespread blackouts with the consequent eventual devastating outcomes measured in terms of the huge economic casualties and the possible human fatalities. The main purpose of this work is to mitigate inter-area power oscillations. This article explores the effectiveness of dual thyristor controlled braking resistor units with Interval Type-2 fuzzy-based centralized architecture for neutralizing the jeopardy of inter-area power oscillations in Kundur’s two-area test system using MATLAB™/Simulink environment. The effectiveness of the proposed scheme is examined by considering four case studies with different degrees of severity. The simulation results show that the proposed scheme is simple yet effective in treating the inter-area oscillations appropriately under the considered case studies.

“…A modern class of FLCs has emerged to the Artificial-Intelligence based control applications, namely, Interval Type-2 FLCs [17]. Interval Type-2 FLCs have been recently implemented for solving many power system dynamic problems as a more superior alternate for type-1 FLCs [17][18][19][20][21][22][23]. Interval Type-2 FLCs are based on the concept of Interval Type-2 Fuzzy Set (IT2 FS) which was first introduced to the academic community by Lotfi Zadeh in 1975 as a sequel to his traditional Type-1 fuzzy set (T1 FS) concept [24][25][26].…”

Torsional Oscillations Mitigation via Interval Type-2 Fuzzy Logic Brake Control

Turbine-generator shaft torsional oscillations is an interdisciplinary power system dynamic problem because it encompasses mechanical and electrical sectors of power grids. They give rise to a premature expenditure of fatigue life of the turbine-generator shaft metal which could lead to shaft cracks. This paper introduces an interval type-2 fuzzy logic controller to regularize the dynamic braking interventions of a novel braking resistor model for mitigation of torsional oscillations resulting from unsuccessful autoreclosure procedures near generation stations. The effectiveness of proposed scheme is elucidated by considering the unsuccessful autoreclosure of three-phase-to-ground fault in a single machine infinite bus power system via MATLAB/Simulink-based modeling and simulation environment with the help of interval type-2 fuzzy logic controller toolbox. The comparative simulation results with and without the suggested mitigation regime show that the proposed scheme is effective in the mitigation of torsional torque oscillations
