Figure 8. The ARDA microgrid management based on dc bus voltage.

Because of the dc nature of many renewable sources,
energy-storage technologies, and modern loads, integration of resources and loads in a dc bus is attractive in
reducing the footprint of the installations, increasing the
efficiency, and eventually reducing the cost of the
microgrid. Lack of standardization, lack of dc-rated components, and obstacles in safety approval are factors
impeding the implementation of dc microgrid demonstration projects. Achieving widespread deployment of dc
microgrids will require, in addition to standardization and
lower hardware cost, effective means to reduce the engineering cost of microgrid projects. Concepts that approach
the plug-and-play paradigm so successfully used in the
computer industry will have a better chance of achieving a
widespread market acceptance. ARDA Power's proposed
solution, based on using the energy-storage elements to
regulate the dc bus and as the energy manager for the system, meets this requirement.
