Advanced Controller Tuning for Grid Stability
This research rigorously evaluated five distinct control strategies—PID, PIDn, FOPID, TID, and PIDA—for Automatic Generation Control (AGC) in a two-area power system. The effectiveness of these controllers was optimized using a suite of seven advanced metaheuristic algorithms, including Artificial Rabbit Optimization (ARO), Chernobyl Disaster Optimizer (CDO), Modified Chernobyl Disaster Optimizer (mCDO), Golden Jackal Optimization (GJO), Honey Badger Algorithm (HBA), Mont-Flame Optimization (MFO), and Spider Wasp Optimizer (SWO). The objective function, Integral of Time-Weighted Absolute Error (ITAE), served as the primary metric to determine optimal parameter sets, ensuring that the chosen controller-algorithm combination delivers the most stable and responsive system performance.
Next-Generation Optimization with mCDO
The Modified Chernobyl Disaster Optimizer (mCDO) stands as a core innovation of this study. It significantly enhances the original CDO algorithm by integrating two novel search mechanisms: a neighborhood-global integration strategy and a wandering-based exploration strategy. These enhancements address the limitations of basic metaheuristics by ensuring a superior balance between exploration (discovering new potential solutions) and exploitation (refining existing good solutions). This dual approach allows mCDO to navigate complex, multimodal optimization landscapes more effectively, leading to faster convergence to optimal parameters and more precise tuning compared to its predecessors and other tested algorithms.
Ensuring Robust Frequency Stability
Maintaining zero-frequency deviation under dynamic and continuous load variations is paramount for interconnected power systems. The study meticulously analyzed system responses in terms of undershoot, overshoot, and settling time across various controllers and optimization algorithms. The FOPID controller, when tuned by mCDO, consistently demonstrated superior dynamic performance. It achieved rapid stabilization, minimal transient peaks (undershoot of -0.1480 Hz and overshoot of 0.0083 Hz), and the quickest recovery to steady-state conditions, affirming its capability to ensure robust frequency stability and efficient power system operation in real-world scenarios.

Real-world Resilience: FOPID-mCDO Under Dynamic Loads
The FOPID-mCDO framework's robustness was rigorously tested under continuous and unpredictable load variations, simulating realistic operating conditions in a multi-area power system. Unlike studies limited to static scenarios, this evaluation confirmed the controller's reliable performance in dynamically changing environments. The system exhibited minimal frequency deviations and maintained stability without significant oscillations, even with repeated high-power load connections and disconnections. This demonstrates the FOPID-mCDO combination's capability to provide a fast and reliable response to real-world grid disturbances, ensuring continuous power system equilibrium and operational integrity.
