Smart Energy Management with Automation of Power Switching using Source and Load Prioritization

Abstract

In this project, an effective home energy management is done. It intended to provide 24 hour
back up to the domestic appliances by using renewable energy, commercial ac supply or UPS
depending on the availability. Renewable energy is given main priority to drive load. If the
renewable energy demand is not met, some loads can automatically switch to alternative
sources like ac supply or UPS. If the renewable energy is sufficient, in addition to drive all
loads, it is used to store UPS battery. To do effective load prioritization and switching of the
sources, microcontroller controlled relay circuit is designed here. In future, the same project
is planned to designed and implemented for industrial loads.
