Abstract
Active power imbalance between electrical power generation and demand causes deviation in frequency and tie-line power of an interconnected power system. Load Frequency Control (LFC) is an epoch-making method to maintain nominal frequency and tie-line power of a power system. Also, continuous research is going on to improve the effectiveness of the LFC mechanism. In this scenario, this paper contributes to design an effective controller configuration for LFC mechanism of a nonlinear multi area interconnected system. A cascaded combination of Proportional-Integral controller with Fractional Order Proportional-Derivative controller (PI-FOPD λ N) has been proposed in this work. One of the popular whale optimization algorithm (WOA) has been deployed to optimize the proposed controller parameters. The proposed scheme has been compared with several conventional controllers and its robustness has been checked by subjecting it to variation in power system model parameters. Deregulation environment of power system is also incorporated for more realistic approach.
