Using a negative load for laod shedding

[Sebastian Wurm]

I was wondering if I could use a negative, controllable load for load shedding instead of the method using "dummy" generators?

Something like this: 

network.add("Load", "actual_load",

            bus="main_bus",

            p_set=[50]*24)  # Fixed demand of 50 MW

network.add("Load", "load_shedding",

            bus="main_bus",

            p_set=0,  # Starts with zero shedding

            controllable=True,  # Solver can adjust it

            min_pu=-1,  # Can go negative (i.e., reduce demand)

            max_pu=0,  # Cannot increase demand

            marginal_cost=500)  # Lower cost, activated first

No, by design, the PyPSA load component is not controllable. Load shedding should be modelled with a generator.

Thanks for the clarification!
I am new to using PyPSA and just found this forum, so I will probably post some more questions in the future ;)
