The emergence of microgrids with embedded energy sources ("prosumer") to provide increased reliability and resiliency in the supply of energy to customers is not a new concept. One of the challenges with these systems - in particular, where the energy source is "behind-the -meter rooftop PV - is the strain it places on the business structure that regulators require utilities to work within as these types of PV systems continue to grow.

 

Additionally, the "typical " microgrid is an extension of the utility AC distribution network when interconnected to the grid (normal configuration) thus prone to the power quality and resiliency issues that come with the AC grid.

 

A novel microgrid concept has been developed that addresses these issues and provides additional benefits by utilizing DC as its distribution network, with all energy sources owned and operated by the utility. Tampa Electric has embarked on a Pilot Project to implement such as system.

 

This presentation will walk through a general overview of this novel microgrid concept with a few of its key features highlighted, the processes and challenges in the creation of this Pilot Project, and some early lessons learned.
