САЖЕТАК / ABSTRACT:
Renewable energy sources, such as solar panels and wind turbines, play a crucial role in modern power supply systems, significantly reducing dependence on fossil fuels and contributing to sustainable development. Various software tools and programs can be used for the analysis and calculations of systems that incorporate renewable energy sources. In this study, MATLAB GUI (Graphical User Interface) was utilized as a tool for creating interactive applications with a graphical interface, making it easier to work with complex algorithms and analyses. The paper presents an application designed for the fundamental analysis of a hybrid power supply system intended for isolated consumers. The system consists of photovoltaic modules, wind turbines, battery storage, a diesel generator, and power conversion devices, all working together to provide power to consumers with variable demand. This hybrid system represents an efficient solution for supplying electricity in locations where connection to the public distribution network is not feasible. The application allows users to interactively adjust system parameters, such as temperature, solar irradiation, wind speed, and battery capacity. Before performing the analysis, users can upload time-series data related to energy consumption, ambient conditions, and weather parameters. Additionally, the application leverages neural networks to predict 24-hour load and generation profiles, which are then used in the analysis. The application also visualizes energy production from renewable sources, monitors battery charge levels, and determines when the diesel generator needs to be activated. The control logic, operating with an hourly time resolution, prioritizes renewable energy sources first, followed by battery storage, while the diesel generator is activated only when necessary. Testing the application under various weather conditions and load levels has demonstrated the efficiency of the proposed system and its ability to adapt to environmental changes and energy demand fluctuations.
