I’m setting up a PyPSA model and have an issue where I’ve used two unidirectional links to model interconnector imports and exports (as they have different p_noms in each direction). However, when I’ve extended this to include expansion modelling the model is importing and exporting at the same time. Should I just model this as a bi-directional link setting p_min and p_max to the required values or can I add a constraint to restrict importing and exporting at the same time (appears to be caused due to the ramp limits).

enter image description hereI want to optimize one hydro reservoir over multiple time snaphshots using PyPSA and Python.
On Pypsa support page, I used the Two chained reservoir example as a starting point, even if i want only one reservoir in my case.
