Transit Search Optimization (TSO) based Tilted Integral Derivative (TID) Controller for Frequency Regulation of Deregulated Power System

This paper introduces a novel approach to address the challenges of frequency and tie-line control in hybrid systems within a deregulated environment. The test system considered in this study operates under a deregulated regime, encompassing diverse power sources, including hydroelectric systems, wind energy sources, thermal power plants, and gas turbine-based power plants. The primary focus of this research is to effectively minimize variations in frequency under load change. Maintaining frequency regulation is vital for ensuring system stability, and thus, precise tuning of the controllers becomes crucial to dampen oscillations. The Tilted Integral Derivative (TID) controller is a novel control strategy that has recently emerged as a promising solution for addressing the challenges posed by complex and nonlinear control systems. For tuning of TID controllers parameters, newly developed Transit Search (TS) optimization algorithm has been used by minimizing the ITAE as the objective function. Effectiveness of TSO based TID controller is analyzed through comprehensive simulations conducted under a deregulated environment with varying power agreements and load change scenarios. The results demonstrate the superior performance of the proposed method and ensuring the stability and reliability of the hybrid power system under dynamic operating conditions.
