SMART ENERGY MANAGEMENT FOR HYBRID POWER GENERATION SYSTEM

Abstract

The availability of more than one source for a given load, provides an uninterrupted supply
of power. And in today’s world of increased pollution and depletion of nonrenewable resources,
using renewable sources to trap power will provide solution to such problems. Two sources of
energy, namely, solar energy and wind energy are considered in this work. Both of these are
renewable energy sources and their operational performances are not the same for all hours of the
day and also for all seasons of the year. The project proposes an Energy Management System (EMS)
to provide continuous power supply for the users employing hybrid power generation units. Based on
the load requirement, either solar or wind energy can be made to supply power. The Power from AC
mains is utilized at the time of interruption of both solar and wind energy. Embedded system using a
high speed PIC microcontroller is used in the project for automation of the switching between the
sources. The whole system is designed in a compact and in a cost effective manner to provide easy
means of operation. Also, the system operation involves fast operating speed, RISC architecture and
some features such as internal ADC. As the entire progression takes place without much human
intervention, the loss in electricity can be reduced on a huge scale during the distribution.
