A Real Time and Development Integration of Renewable Sources of Energy into Power Grid Application

Abstract

Thehuge,evergrowingdemandforelectricalenergy has hitherto been primarily met through the combustionof fossil fuels, and conversion of heat liberated therefrom. Therelentlessexploitationoftheseresourceshasraisedquestionsregarding emission of greenhouse gases, particulate pollution,and theirharmfuleffectsonenvironment.Italsobringsintofocus the sustainability of generation to satisfy the demand forenergyinthecomingdecades,fromfuelswhicharenotinexhaustible. Renewable sources of power such as the sun, thewindandthetidesoffersolutionstotheseissues.ThecontinuouslyfallingcostofSolarandWindgenerationtechnology has also made this option economically viable.
