Özet
The study investigates gain-phase margin (GPM) based stability analysis for a time-delayed single-area load frequency control (LFC) system with fractional order proportional-integral (FOPI) controller. The extensive usage of open communication networks in power system control causes inevitable time delays. To compute such delays, an analytical direct method determined the imaginary axis crossing of roots of the characteristic equation is proposed for desired gain and phase margins (GPMs) and a large set of FOPI controller. Finally, for time-delayed single area LFC system with FOPI controller, results obtained are verified by using the time-domain simulation studies in Matlab/Simulink and the quasi-polynomial mapping-based root finder (QPMR) algorithm which locates quasi-polynomial roots in time delay systems.
