Voltage collapse in some cases

[marota]

You might want to keep loads and generators on a same node to avoid voltage collapse

such as in this case on scenario jan_28_1

At substation 26, there is a big load. While the node of the load is a PV node with regulated voltage.

If you split them with this action for instance
grid2op_topo_sub_26=[1, 1, 2, 2, 1, 1, 1, 1, 2]

This action will:
- NOT change anything to the injections
- NOT perform any redispatching action
- NOT modify any storage capacity
- NOT perform any curtailment
- NOT force any line status
- NOT switch any line status
- NOT switch anything in the topology
- Set the bus of the following element(s):
- Assign bus 1 to line (extremity) id 36 [on substation 26]
- Assign bus 1 to line (extremity) id 37 [on substation 26]
- Assign bus 2 to line (extremity) id 38 [on substation 26]
- Assign bus 2 to line (extremity) id 39 [on substation 26]
- Assign bus 1 to line (origin) id 40 [on substation 26]
- Assign bus 1 to line (origin) id 41 [on substation 26]
- Assign bus 1 to line (extremity) id 56 [on substation 26]
- Assign bus 1 to generator id 14 [on substation 26]

You get this voltage collapse at -15%:
