Multifunction controller and DC revenue meter for nanogrid

The development and growth of microgrids in DC require revenue meters to quantify the amounts of energy transferred, to reduce the losses caused by DC / AC and DC / DC conversions and to share the resources of the energy generated and stored efficiently. As a result, this document presents the development of a DC multifunction revenue meter system, which operates at 140 VDC and its main features for interconnecting to operate as a shared economy power system.
