Integral-Tilt-Derivative Controller Based Performance Evaluation of Load Frequency Control of Deregulated Power System.

This paper introduces a fractional-order-calculus-based integral-tilt-derivative controller (I-TDC) for load frequency control (LFC) of two-area multi-source restructured interlinked power system. The studied system consists of thermal, hydro, and nuclear-generating units with generation rate constraints nonlinearity. To obtain the optimized value of I-TDC coefficient and other parameters, water cycle algorithm (WCA) is employed. To investigate the competence of WCA tuned I-TDC over the proportional-integral-derivative controller and integral-proportional-derivative controller, the comprehensive examinations under the effect of different contract scenarios are carried out.
