What is a
Microgrid
Micro-grids are electricity distribution systems containing loads and distributed energy resources, that can be operated in a controlled, coordinated way either while connected to the main power network or while islanded.1

Types of Microgrids
1. Customer or True Microgrid (µgrids) – self governed, downstream of a Point of Common Coupling (PCC) they fit into current technology.
2. Utility or Community Microgrid (mgrids) – technically similar to the Customer or True grid but it involves utility owned infrastructure.
3. Virtual Microgrid (vgrids) - a concept that coordinates multiple distributed generation resources to operate as a True or Utility microgrid.
4. Remote Power Systems (rgrids) - separate from the traditional grid, isolated, involve similar technology, so closely related they are commonly described as microgrids.

The Energy Challenge An island power system would typically run 24 hour per day , 7 days per week on a diesel generation power plant. Factors that affect the operation of the system includes fluctuation in diesel fuel prices, fuel transportation costs, storage, and ongoing maintenance costs .
The Island Microgrid Solution Integrating renewables with the existing energy generation assets, adding battery energy storage in an environmentally controlled shelter with a performance monitoring interface can lead to the following . The Benefits
50% Reduction in Generator Run Time
50% Savings in fuel consumption and transportation costs
