Energy Management System for Hybrid Renewable Energy System

Abstract

This project explains about the demand side load management system based on the energy that is generated from a hybrid power system and the loads are managed according to the generation level. Here we are using “Photovoltaic cell” and “Wind energy” as sources for generation of energy. The generated energy from photovoltaic cell and wind energy is stored in the battery. The percentage of battery is monitored and the loads are managed according to battery level. Such as if battery is 100% charged then all loads will be in ON condition and if the battery charge drops below some desired level then as programmed to the microcontroller ,  the supply to the low priority load is interupted . Micro-controller gives a different priority for the different load according to battery charging percentage. Thus by this project the loads can be managed with the supply level at the load side itself rather than adjusting the supply side. Thus unnecessary loads at peak hours can be eliminated based on the generation.
