Optimal Design of Fractional Order Tilt-Integral Derivative Controller for Automatic Generation of Power System Integrated with Photovoltaic System

Abstract

Renewable energy has recently attracted a lot of interest due to its low cost and long-term sustainability. Integration of a photovoltaic (PV) system into an existing power system on a large scale is a challenging task. Due to irregular irradiance and an inertia-less system, frequency regulation is a cumbersome task. So, load frequency control is recommended in this article for multi-area power systems that include PV and thermal plant sources. The performance of four competing controllers, namely proportional integral derivative (PID), fractional-order PID, tilt-integral-derivative (TID), and fractional-order TID (FOTID), is investigated and compared. For obtaining the best-performing parameters, the honey badger algorithm (HBA) is implemented. Furthermore, uncertainty is taken into account by varying the system parameters from -20% to 20% in steps of 10%. The suggested competing controllers' performance is evaluated using a dynamic load. The performance of the proposed HBA-based FOTID controller is also studied against a randomly varying load applied in area-1. The work is further extended to a four-area system. Finally, it is observed that the HBA-based FOTID controller exhibits superior performance in maintaining the system's frequency and tie-line power when it is subjected to a disturbance.
