A Review of Smart Integrated Renewable Energy System

This paper examined seven studies spanning solar–wind hybridization, multi-objective sizing, real-time energy management, smart-grid integration, micro grid monitoring and AI/IoT techniques. Across them, source integration, suitable power conversion, coordinated storage and reliable measurement emerge as the main requirements for making better use of renewable energy. The literature also shows that model assumptions, site conditions, communication limits and scarce field validation restrict how widely the results can be applied. A solar–wind system that pairs battery storage and converters with an ESP32 and voltage/current sensors is a practical way to watch how renewable generation and the load behave. It should be evaluated with timestamped measurements under several operating conditions, and efficiency, renewable contribution and load availability should be computed from stated definitions and measured data. Future work may add source forecasting, validated anomaly detection, optimized sizing and closed-loop energy management once the basic measurement and protection functions are verified.
