Abstract
This contribution presents one developed solution for parallel photovoltaic
energy generators based on a distributed architecture with individual DC-DC
converters, named optimizers, connected to an intermediary high voltage direct
current (HVDC) bus. This power bus also supports the communication between
optimizers and a central controller using the power-line communication (PLC)
approach. Then the optimizers are optimized for an interface output stage
assuming the PLC on the HVDC bus. This work, from the conception to the
realization of a prototype, concerns the analysis of the nature of the pertinent
information to the exchange between the converter and the central controller.
The information can include the I–V characteristics and the temperature of the
individual sources. The development of an electronic prototype that integrates
recently available components is made and the technological constraints at the
possible available frequency bandwidth are considered. The concrete realization
will be presented in fine.
Keywords: power-line communication (PLC), high voltage direct current
(HVDC), smart DC-DC converter, optimizer, renewable energy.
