News challenges and protocols for DC bus for Smart Buildings
Résumé
This paper present news trends for electric DC
microgrids for smart Homes and smart cities. With the emer-
gence of the renewable energies, the DC bus could optimize
electricity power efficiency for smart home (green home). Since
the initial choice for alternative current transportation in 1880,
the electrical architecture distributions haven’t been change with
one direction distribution to the consumers through high voltage
lines. But AC power distribution therefore is so wasteful due
to number of converters AC/AC and AC/DC with consequent
energy losses (15% energy per converter). Nowadays most of
renewable energy sources as solar panel are DC and all modern
appliances are also DC powered (LED lighting, IT, electric car ..).
We propose a smart DC grid distribution architecture for smart
homes based on 2 voltages levels 48 VDC (Power over Ethernet)
and 380 to 400 HVDC bus to improve electrical efficiency.
Under the scope of ANR-C3µ project we present a microgrid
DC bus with distributed control command for optimal energy
resources management based on self-consumption and peak
shaving for the grid. For data exchanges we will use Power
Line Communication (PLC) now widely used in wide range
of AC application (IP over AC) for the DC line and to pilot
the DC microgrid. With the expérimental results feedback we
could analyze the communications performances and the design
for a microgrid control/command system in smart building
applications.
