Demonstrating the Predominance of Time Delays on Frequency Regulation of Dual Area Realistic Power System under 2DOFPID Controller

TLDR: In this article , the authors demonstrate the importance of time delays on the performance of dual area realistic power systems (DARPS) under the regulation of two degrees-of-freedom PID (2DOFPID) controller fine-tuned with modern heuristic optimization approach of seagull optimization algorithm (SOA).

Abstract: In this paper, the investigation is concentrating on demonstrating the prominence of time delays on the performance of dual area realistic power systems (DARPS). Step load perturbation (SLP) of 10% is injected in area-1 of DARPS for analysis purposes under the regulation of two degrees-of-freedom PID (2DOFPID) controller fine-tuned with modern heuristic optimization approach of seagull optimization algorithm (SOA) subjected to the integral square error (ISE) index. However, the efficacy of 2DOFPID is showcased upon comparing with PI/PID controller performances. The investigation is performed on DARPS with and without considering time delays and the simulation results deliberate the significance of time delays on frequency regulation of DARPS.
