Abstract

Fuel cells are essential components of renewable energy sources. There are many industrial applications related to them. One of the sample applications is electrical power compensation systems (EPCS). EPCS, as one of the essential parts of electrical installations, are used to eliminate reactive power. In this study, the effective control of a static compensation system developed for fuel cell power-generation plants is studied to eliminate the reactive power caused by the loads. The static compensator is a five-level inverter consisting of 24 IGBTs. Here, advanced and hybrid controllers are used and tested together. In the study, fractional-order proportional–integral–derivative controller-based model predictive controller (MPC), tilt-integral-derivative controller-based MPC controller, and hybrid fractional-order proportional-tilt-integral-derivative-based MPC (FOPTID-MPC) controller are used, and their efficiencies compared in terms of transient response characteristics and an error-based performance function. In addition, the parameter adjustments of the controllers are made using the Pathfinder Optimization Algorithm. The effectiveness of the proposed FOPTID-MPC controller scheme is shown.
