- SonatrachProject Intern - Restructuring a Solar Energy Production System for Techno-Economic ImprovementENERGY AND UTILITIESMay 2024 - June 2024 (1 month)Illizi, AlgeriaOptimization of a photovoltaic system with electrochemical storage for a gas well. The study revealed oversizing in the existing system. A heuristic MATLAB algorithm was developed to minimize energy cost and reduce power loss probability. Results demonstrated a significant reduction in energy cost, improved system reliability, and a potential gain up to 987% compared to the existing system.
