Standalone PV system implementation and DC load consumption management using Raspberry PI 4

Abstract

The rise demand for clean and sustainable energy sources has led to the widespread adop- tion of PV systems. To optimize their performance and efficiency ,i ti scrucia lt ostud yand analyze their behavior. In this project, we propose a modeling and simulation approach using MATLAB Simulink to simulate a standalone PV system. Additionally, we also designed a stand-alone PV system prototype using the Raspberry Pi 4 and ESP32 microcontroller for real-time monitoring and controling to demonstrate how this system is implemented practi- cally and test our energy management system algorithm performance with actual hardware implementation. The simulation model in MATLAB Simulink incorporates components such as PV panels, batteries, DC-DC converters, and DC loads. By simulating various scenarii, such as changes in solar irradiance and load demand, we can evaluate the system’s performance and assess the effectivenes so fdiffere ntcontr olstrategie s.Furthermor e, int hepractic alimplementa- tion, the Raspberry Pi 4 acts as the central control unit, gathering data from sensors and communicating with the ESP32 microcontroller which serves as battery data collector. This study contributes to the design, analysis, and implementation of standalone PV systems by combining the power of MATLAB Simulink simulation software with the flexibility and control capabilities of Raspberry Pi 4 and ESP32.
