Future DC Smart Homes: Key Power Electronics Development

Abstract

The advent of rooftop photovoltaics (PV), energy storage systems like a battery (BESS) and high capacity electric vehicles (EVs) is changing the landscape of electrical distribution rapidly. Traditional electricity consumers like households, buildings (both commercial and residential) are augmented with these emerging technologies which are turning them into "Prosumers" (producer and consumer). This is beneficial to the current radial grid structure as Prosumers are inherently more self-sufficient in terms of energy and thus provide grid-relief from congestion and will potentially delay or obviate the need for expensive grid upgrades. To fully realize the potential of these multiple sources and loads as a single dispatch-able prosumer, this thesis focuses on developing electronic hardware to accurately control these individual elements which result in an intelligent, flexible and safe grid.
