Abstract
Background/Objectives: The essential goal of the Automatic Generation Control (AGC) framework is to limit the transient deviations in the area frequencies and tie-line power oscillations and to guarantee their steady-state errors to be zeros. Methods: The article proposes a new cascade Two Degree of Freedom PID including filter along with Fractional Order PID together with filter (2DOF-PIDN-FOPIDN) regulator which are designed using Buzzard Optimization Algorithm (BUZOA) technique and executed in the secondary controller of the AGC loop of a two-region thermal-hydro-wind restructured power system. The proposed novel 2DOF-PIDN-FOPIDN regulator consists of an integer order cascaded controller through a fractional order controller. It guarantees with the aim of the controller intend process be easy to execute and has an outstanding ability to manage parameters improbability, removes steady-state errors, and guarantees enhanced stability as compared with the 2 DOF-FOPIDN regulators. The controller gains and other control constraints were tuned with novel and efficient meta-heuristic optimization techniques such as the BUZOA technique. Further, the AGC loop of the proposed system is enhanced with the application of sophisticated Hydrogen Energy Storage (HES) units connected in the control area and FACTS devises like Interline Power Flow Controller (IPFC) which is also introduced in series with tie-line of the interconnected areas of the restructured power system under different possible exchanges. Findings and Novelty: The reproduction results uncover that the predominance of a new cascade 2DOF-PIDN-FOPIDN regulator, the unique presentation of AGC system of a two-region interconnected restructured power framework has worked on as far as less peak variation and settling time of region frequencies and tie-line power in different transactions as contrasted 2 DOF-FOPIDN regulators. Moreover, the execution of HES and IPFC units effectively arrest the fundamental decrease in frequency like the tie-line power deviation after an abrupt load disturbance to give the critical advantage of stability.

Highlights
The effective activity of interconnected power systems involves the coordinating of allout generation through absolute demand in load and the related losses in the system
The Buzzard Optimization Algorithm (BUZOA) enhancement procedure is utilized to choose the ideal boundaries of 2DOF-FOPIDN regulators with the objective to restrict Integral Square of Area Control Error (ACE) signals are expressed in Eqn (10)
The BUZOA technique has been utilized to decide the optimal parameters of the cascade 2-DOF-PIDN-FOPIDN regulator
Summary
The effective activity of interconnected power systems involves the coordinating of allout generation through absolute demand in load and the related losses in the system. An AGC conspires principally coordinates a reasonable control system for an interconnected power system to bring the frequencies of every area and the tieline power back to an exceptional set point worth effectively after the load change. Further could enhance the system performance, fractional-order PID regulators have been considered and it gives adaptability in controlling purposes which assists with arranging the AGC issues and excellent competence of managing parameter ambiguity, removal of steady-state error, and ensures enhanced constancy (7). The coordinated control activities between ESS and FACTS devices in the AGC system have been found to manage the system states in a quick and efficient way(12) In this examination, the improvement of the AGC system a refined utilization of HES units associated with the control area of the proposed power system. A FACTS device like IPFC is presented in series with tie-line interconnected regions
