A Modified Constricted Quantum Class Topper Optimization Algorithm for Tuning FOPI Stabilizer for One Machine Infinite Bus System

An oscillation with frequency of low range in the grid is damped out with power system stabilizer (PSS). The conventional PSS will not provide the flexible operation in real power system. In this paper, a fractional order PI (FOPI) along with wash-out filter is used for one machine infinite bus (OMIB) system. The stabilizer gains are optimized by a modified constricted quantum class topper optimization (CQCTO) algorithm. Integral time square of speed deviation (ITSSD) is taken as the fitness function. It is verified for one machine infinite bus (OMIB) system with IEEE DC-1 type exciter. The comparison of CQCTO-FOPI is presented with class topper optimization (CTO)-FOPI stabilizers and existing results.
