Optimal tuning of tilted integral derivative (TID) controller parameters for multi-area power system and frequency regulation using pelican optimization algorithm (POA)

Abstract

Power generation plays a vital role in any electrical system, and load frequency control maintains its stability. Modern systems use effective load frequency controllers that maintain the frequency of the system. In this work, a fractional order tilted integral derivative (TID) controller is optimized by using the Pelican optimization algorithm for load frequency control in modern integrated power systems. The performance of the controller based on the pelican optimization algorithm is computed with the help of a multi-area interconnected system containing a hydro plant, a gas plant, and a thermal power plant. In this work, ITAE (integral time absolute error) and ISE (integral square error) are considered objective functions. With the tuning of the TID controller by the Pelican optimization algorithm, the results were tested by the already proposed methods as the Particle swarm optimization technique and Archimedes optimization algorithm (AOA). In this work, a step disturbance was given to area 1, and the response of the controller was observed. While evaluating the controller parameters, the system nonlinearity is also taken into consideration, such as generation rate constant (GRC), communication delays, etc. It was seen from the results that the enhanced performance of the system was obtained, which improves the power system stability and management for interconnected systems.
