Enhancement in Frequency Regulation of Two Area Conventional Interconnected Power System with AC-DC Lines

This paper purports the development of a tilt-integral-derivative-filter (TIDN) controller for the dynamic regulation of two area conventional thermal hydro (TACTH) system. The key objective of this investigation is to operate the TACTH system effectively and stable under perturbations. However, the analysis is initiated for the step load disturbance (SLD) of 10% in area-1. The investigation is performed under the monitoring of the water cycle optimization (WCO) algorithm-tuned TIDN controller. Moreover, the efficacy of the suggested controller is demonstrated with other extensively used controllers in the literature. The communication time delays (CTDs) are perpetuated with the TACTH system with the intention of performing the investigation near to practicality. The consequence of CTDs on TACTH system response is showcased and the territorial control mechanism is adopted to further enhance the dynamical behavior by laying the high voltage DC line with the system.
