MICrogrid PROJECTS | Microgrid Project

It's between the net and the island.
Keep multi-energy in the same control target.

Real physical system x digital sandpad validation x auditable chain of evidence to keep the grid, voltage, energy storage, diesel generators and critical loads clear in normal, disturbed, isolated islands and reconnected.
