GenericCHP bug when total power loss at max. output power is higher than at min. output power

See original GitHub issue

Hi, there is a bug in the GenericCHP component in oemof-solph.

When i create a motoric chp where the total power loss at the maximum output power point is higher than the power loss at the minimum output power point, then the motoric chp does not produce any output power.

I have added the motoric chp example file from the oemof examples and only changed the following two lines to produce the bug:

H_L_FG_share_max=[0.11 for p in range(0, periods)],
H_L_FG_share_min=[0.10 for p in range(0, periods)],

I used the latest release: oemof-solph 0.4.1

The complete example file is attached. motoric_chp.zip

I remember that I stumbled across this issue some time ago. For some reason, the slope of the min line must always be steeper than the slope of the max line. I will dig into my files and ask my colleagues, if they remember.

I will close this issue as this seems to be a very specific case only, if you don’t think so, please feel free to reopen 😃.
