Abstract Time‐delayed systems frequently appear, especially in sectors such as fluid flow processes, chemical procedures, and the food industry. This paper addresses optimization of parameters for a fractional order PID (FOPID) controller, which is used to control time‐delayed system, using five distinct algorithms inspired by nature. These are NewBAT, Cuckoo search (CS), Firefly (FF), Gray Wolf Optimizer (GWO), Whale algorithm (WOA). The FOPID controller parameters, namely K P , I D λ μ have been optimized these algorithms. During process, integral time absolute error (ITAE) was considered primary measurement criterion. In addition this value, maximum overshoot, settling time, reach values were examined. Simulations conducted with obtained tested system's resilience disturbances introduced at output, responses also evaluated during tests. reactions determined different reference inputs analyzed, results presented graphs tables. efficiency reliability substantiated comprehensive statistical analyses. analyses play critical role selection objective evaluation results. Simulation studies Matlab Simulink environments. FOMCON Toolbox fractional‐order processes.

Optimized Coordination of Distributed Energy Resources in Modern Distribution Networks Using a Hybrid Metaheuristic Approach

Processes, Год журнала: 2025, Номер 13(5), С. 1350 - 1350

Опубликована: Апрель 28, 2025

This paper presents a comprehensive optimization framework for modern distribution systems, integrating system reconfiguration (DSR), soft open point (SOP) operation, photovoltaic (PV) allocation, and energy storage (ESS) management to minimize daily active power losses. The proposed approach employs novel hybrid metaheuristic algorithm, the Cheetah-Grey Wolf Optimizer (CGWO), which synergizes global exploration capabilities of Cheetah (CO) with local exploitation strengths Grey Optimization (GWO). model addresses time-varying loads, renewable generation profiles, dynamic network topology while rigorously enforcing operational constraints, including radiality, voltage limits, ESS state-of-charge dynamics, SOP capacity. Simulations on 33-bus demonstrate effectiveness across eight case studies, full DER integration (DSR + PV SOP) achieving 67.2% reduction in losses compared base configuration. By combining CO GWO, CGWO algorithm outperforms traditional techniques (such as PSO GWO) avoids premature convergence preserving computational efficiency—two major drawbacks standalone metaheuristics. Comparative analysis highlights CGWO’s superiority over algorithms, yielding lowest (997.41 kWh), balanced utilization, stable profiles. results underscore transformative potential coordinated enhancing grid efficiency reliability.
