Plug-in vehicles can be a means to increase the amount of renewable energy within a microgrid. Properly designed pluggable hybrid vehicles will improve grid reliability and stability. This presentation was a plenary address at the Automotive Research Center annual meeting, and it addresses some of the design components needed to make vehicles and microgrids work together well.
