A microgrid is a group of interconnected loads and distributed energy resources that act as a single controllable entity, with respect to the overall grid.
It can connect and disconnect from the main grid to operate in “grid-connected” or “island mode“.
Within microgrids are one or more kinds of distributed energy: solar panels, wind turbines, combined heat & power and generators that produce its power.
Benefits to microgrids are:
-
Provide efficient, low-cost, clean energy
-
Improve the stability of the regional electric grid and increases reliability and resilience
-
Reduce grid “congestion” and peak loads
-
Enable highly-efficient CHP (combined heat & power), reducing fuel use and carbon footprint
-
Integrate CHP (combined heat & power), renewables, thermal and electric storage, and advanced system and building controls
-
Offer grid services including: energy, capacity, and ancillary services
-
Support places of refuge in regional crises and first responders
-
Use local energy resources and jobs
-
Diversified risk rather than concentrated risk
-
Using electric and thermal storage capabilities, a microgrid can provide local management of variable renewable generation, particularly on-site solar
-
When properly designed, a regional power grid that combines both large central plants and distributed microgrids can be built with: less total capital cost, less installed generation, higher capacity factor on all assets, and higher reliability.
