Advanced microgrids have been identified as being a necessary part of the modern electrical grid through a two DOE microgrid workshops,1’2 the National Institute of Standards and Technology,3 Smart Grid Interoperability Panel and other related sources.More
With their grid-interconnectivity advantages, the integration of advanced microgrids will improve system4 energy efficiency and reliability and provide enabling technologies for grid-independence to end-user sites. One popular definition that has been evolved and is used in multiple references is that a microgrid is a group of interconnected loads and distributed-energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode. Further, an advanced microgrid can then be loosely defined as a dynamic microgrid.
The value of microgrids to protect the nation’s electrical grid from power outages is becoming increasingly important in the face of the increased frequency and intensity of events caused by severe weather. The integration of advanced microgrids will serve to mitigate power
