cost model changed to accommodate all ghost turbine case (i.e. AEP=0) & a new example added
This has been lying around in my computer for a while since the capacity constraint is added. It is just ensuring the economical model does not fail in case there is zero AEP and also ensures that a single ghost turbine cost is zero.
The newly added example test did not pass due to pyWake I think.
I believe once the pyWake is settled with respect to the required inputs to
AEPCalc = AEPCalculator(wake_model)
the test will pass.
in my computer it runs fine (except this problem)
@pire could you also have a look to ensure this code does not interfere with the electrical cost .
