Enhancement in AGC Performance of Multi Area Interconnected Power System with Practical Constraints using WCA based PIDD Controller

Abstract

In this paper, a new controller of proportional (P)-integral (I)-double derivative (DD) (PIDD) optimized with a newest optimization approach of water cycle algorithm (WCA) is presented for performance enhancement of automatic generation control (AGC) in dual area hydrothermal (DAHT) system. Analysis of DAHT is accomplished by targeting area-1 with a perturbation of 10% step load (10%SLP). However to investigate the dynamical analysis nearer to realistic practice several constraints have been employed with DAHT system. Moreover, the WCA based PIDD controller efficacy is deliberated with those of classical PI/PID approaches for the same perturbing conditions. Later, the effect of considering communication time delays (CTDs) with the system is clearly authenticated.
