An intelligent power management system for developing a smart grid system

Abstract

The main aim of this work is to create a novel intelligent power management system that can identify synchronization failures of any external supply source to the power grid by sensing frequency and voltage irregularities. Furthermore, in a three-phase system, an automated phase changeover of the load from the missing phase to the next available phase is included to provide continuous AC mains supply. In addition, a solar module with suitable storage capacity is attached to the proposed system to reduce grid energy use and play main energy sources to maximize green energy usage. The electrical loads can be protected by automatically shutting down the system utilizing microcontroller programming. The LCD shows the current supply voltage as well as the overall system's operating frequency. The complete unit will be shut down by the intended controlling unit if any of these parameters increases or lowers over the limit of every separate incoming source, and the system will automatically reconnect following stabilization.
