Abstract
This paper explores the feasibility of supplying electrical power to modern homes using a DC
voltage mains within the house. A bottom-up approach is adopted in the design of the DC supply,
starting with known domestic loads to build a power usage profile based on assumed lifestyle for the
occupants of the house. The load profile is then used to work out cable sizes for the mains
distribution network. It looks at the type of electrical cables to be employed and the calculations
involved in working out voltage drops, and therefore power loss along the cables. The voltage used
in the calculations, was 24 V, as this is the voltage rating of DC appliances and devices. The
methodology is then employed with a range of powers and voltages to work out different possible
load and cable scenarios. The constraints to the analysis and further work are discussed. Economic
analysis is carried out on energy losses, and the advantage of using DC appliances, as against using
AC appliances is discussed. The goal is to build a framework that will provide the necessary tools
that will help in identifying an optimal voltage for the low powered DC home. Previous work is
looked at.
