Load frequency control of a PV–DSTS integrated thermal–hydro power system using a CCSA-optimized fuzzy fractional-order parallel controller

Year: 2026
Type: article
Abstract: Two area multi-unit thermal hydro (TAMTH) system integrated with solar and dish-Stirling solar thermal system (DSTS) is investigated to regulate the frequency disturbance. An adaptive controller with a combination of Fuzzy Logic Control (FLC), Fractional Order proportional integral derivative (FOPID) and 2 Degree of Freedom PID (2 DOFPID) is designed to achieve frequency stability. The decisive parameters of the proposed Fuzzy based FOPID-2DOFPID (FFOPID-2DOFPID) controller are optimized by Crow Search Algorithm (CSA) and craziness factor of crow in CSA (CCSA). The proposed FFOPID-2DOFPID controller is enforced in each area for both thermal and hydro units to contribute a fine-tuned stable power system. The conformation of superiority of projected controller is presented by a comparative analysis with different kind of controllers along with some newly published research works. The comparative simulation performance analysis is performed by considering undershoot, overshoot and settling time of deviations to show the supremacy of the FFOPID-2DOFPID controller.
