Novel Fractional-Order Proportional-Integral Controller for Hybrid Power System with Solar Grid and Reheated Thermal Generator

This paper presents a new fractional-order proportional-integral, (PI)λ (FO[PI]) type structure to investigate the load frequency control (LFC) problem. In literature, some controllers’ extensive tuning options may slow or complicate optimization process. Due intricacy of tuning, even if there are fewer parameters, robust can be obtained. The deviates from standard FOPI, integer PID, PI-PD controllers with same parameters. efficacy tri-parametric controller is examined on two-area interconnected hybrid power system comprising photovoltaic (PV) grid and Reheated Thermal Generator (RTG). order obtain optimal performance lower efforts, novel dual-performance index developed for LFC Various analyses also proven perform better than other optimized recent literature. presented scheme significantly disturbance interruptions, non-linearities, parameter perturbations. It observed that no stability issues due communication time delays. highlighted improvement obtained without adding complex
