comparisons to regional grids and microgriDS

---

The entire regional grid, including both transmission and distribution systems, operates reliably to meet all loads under utility and/or ISO/RTO control.

The regional grid operates under utility or ISO/RTO control.  Each microgrid has its own internal generation and electric loads and operates under independent control interconnected with the grid at a Point of Common Coupling on either distribution or transmission circuits.

The entire regional power grid, including the Resilient Community Grid, operates under utility and/or ISO/RTO control with the microgrids operating independently.   Unlike a microgrid, the Resilient Community Grid has no Point of Common Coupling to the electric grid because it is an inherent part of the grid.

 All loads and generation units are offline and must be restarted by individually re-energizing lines and black-starting generating units. 

Only loads served by undamaged microgrids with adequate fuel supply remain online. The rest of the grid continues to experience the outage.

Only the  Resilient Community Grid and microgrids operate islanded from the rest of the power grid.  Resilient Community Grid operators can flexibly balance loads and generation within the Resilient Community Grid. The Resilient Community Grid can also be used to black start the rest of the grid.

While the Resilient Community Grid secures more critical infrastructure facilities than a microgrid, microgrids within the Resilient Community Grid add a further layer of hardening and protection.  Microgrids within it can also be a resource for the Resilient Community Grid.
