Abstract

The Hybrid Renewable Energy Monitoring and Control System is designed to integrate and manage multiple green energy sources, specifically solar and wind power, into a single cohesive unit. The system utilizes an ESP32 microcontroller to collect real-time data from voltage and current sensors, calculating the instantaneous power output from each source. By implementing a control logic via relay modules, the system can switch between sources or prioritize battery charging based on availability. Data is transmitted to a cloud platform for remote monitoring, allowing users to track energy production and consumption patterns. The outcome is a robust, scalable prototype that demonstrates the efficiency of hybrid systems in reducing dependence on a single energy source and improving overall grid stability through intelligent power management.

Project Description

The increasing demand for sustainable energy has highlighted the intermittency of single-source renewable systems; solar panels do not produce power at night, and wind turbines require specific wind speeds to operate. This project addresses this instability by developing a Hybrid Renewable Energy Monitoring and Control System that synchronizes solar and wind energy to ensure a more consistent power supply. The primary objective is to create a centralized monitoring hub that tracks the performance of both energy sources in real-time and manages the distribution of power to a load or storage battery. The system employs a sensing layer consisting of voltage dividers and ACS712 current sensors to quantify the energy harvested. An ESP32 serves as the brain of the operation, processing these analog signals and executing a control algorithm to determine the most efficient power source at any given moment. To provide immediate feedback, an I2C LCD displays the current wattage and system status, while the integrated Wi-Fi capability of the ESP32 pushes this data to a cloud dashboard for historical analysis. Societally, this project promotes the transition toward decentralized smart grids, reducing carbon footprints and providing a blueprint for off-grid power solutions in rural or remote areas where traditional utility infrastructure is unavailable.
