In the field of telecommunication towers, specifically focusing on Base Transceiver Station (BTS) units, this research presents a revolutionary power supply system that is characterized by optimization and environmental cleanliness. The primary goal is to develop a reliable and continuous energy supply for these isolated units. In order to accomplish this objective, the use of PEMFCs (Proton Exchange Membrane Fuel Cells) is utilized. To provide a constant and controlled voltage of output from the PEMFC to the BTS, a proportional-integral (PI) controller based on improved war strategy optimization is used. The purpose of this controller is to improve the efficacy of the model and efficiently adjust to different operating situations. By conducting a comparison study with other methodologies, the suggested system showcases its advantages in terms of both efficiency and dependability. The research results presented in this study provide a substantial and noteworthy addition to the domain of sustainable energy solutions for communications infrastructure. Through the use of PEMFCs and the integration of modern control algorithms, the suggested system presents a very favorable method for supplying power to telecommunication towers. This approach not only enhances the operational efficiency of these towers but also contributes to the reduction of their environmental footprint.
