Ideas to try:

* Selectively remove scenarios

* Reduce reserve coverage

* Only consider upwards or downwards reserves

Reducing the number of scenarios by 400 (2*200) fixes things.

More investigation has revealed the following for day 5:

Despite constant load shedding and the possibility of shedding reserves, reserve shedding is limited mostly to certain parts of the day (seemingly when there's solar?)
in timesteps 10 and 11, the overall net load forecast error is +ve, leading to negative values of D-. I'm actually very surprised that this didn't lead to infeasibilities... I prevented this from occurring using commit fb3939ace973b4586f28fcfa329bee3afe178d95

There was no error because I had mistaken D+ with D-, hence D- was not being used. Fixed by b0eeb1d71dc300ebc753e0e661ecd4c726680827.

Since no more infeasabilities, I'm considering this issue closed, though I'm sure there's more issues with my model.
