Review on IoT-Enabled Smart Grid Energy Management and notification Systems with Integrating Renewable Energy Sources

The Internet of Things (IoT)-based Energy Management System for a Smart Grid integrating MSEB utility supply, solar energy, and wind energy presents an effective solution for modern energy management challenges. The proposed system utilizes an ESP32 microcontroller as the central controller to continuously monitor and manage multiple power sources while ensuring reliable power delivery to connected loads. By intelligently switching between renewable energy sources and the conventional grid supply, the system improves energy efficiency, reduces dependency on fossil fuels, and promotes sustainable energy utilization. The integration of solar and wind energy sources enhances the reliability and availability of power, while the IoT platform enables real-time monitoring of voltage, current, power consumption, and source status from remote locations. Furthermore, the GSM module provides instant notifications and alerts regarding power source changes, fault conditions, load status, and system performance, thereby improving operational awareness and system reliability. The review indicates that smart grid systems incorporating IoT technologies, renewable energy resources, and wireless communication networks offer significant advantages in terms of energy optimization, cost reduction, environmental sustainability, and user convenience. Such systems are well-suited for residential, commercial, and industrial applications where efficient energy management is essential. Future research can focus on integrating artificial intelligence and machine learning algorithms for predictive energy management, demand forecasting, fault diagnosis, and adaptive load scheduling. The incorporation of battery energy storage systems and advanced communication technologies such as Lora WAN and 5G can further enhance the performance, scalability, and resilience of IoT-enabled smart grid infrastructures.
