The Practical Engineering Youtube channel has a very interesting video on black starts of an electrical grid [0]. Are there any additional challenges in turning

• idiotsecant 2y ago
  There's a pretty big challenge, which is that you aren't turning off a grid at all -just particular transmission lines. Your typical power flows rely on those lines being up, and without them strange conditions can occur. Its sometimes just as bad to have an unusually lightly loaded line as it is to have an overloaded line. Lightly loaded lines with lots of generation end up messing up line voltages due to capacitive loading. You can end up having to shut down a line or taking other remedial action like shutting down generation because not enough power is flowing through a line.
