Add hydropowerlib to list of projects

[Ludee]

I would count the hydropowerlib as part of oemof since it is an extension of the feedinlib.

The hydropowerlib is designed to calculate feedin time series of run-of-the-river hydropower plants. The hydropowerlib is an out-take from the feedinlib (hydropower, windpower and pv) to build up a community concentrating on hydropower models.

There has not been a stable release yet.

Cool idea, but what do you mean be Add to projects. As far as there are others that are the core developers? why not leave it as hydro-python? (Do you plan to re-write the code for adhering to developing guidelines?) sorry- saw that they already use our rules...

Still, do you want to move the repository? Did you talk to Jonas?

... what do you mean be Add to projects.

I added it to the list of "Projects in an early state" in the README.rst
For me this looks like an inventory of existing modules and packages of oemof.
While it is in an external repo, it is like the windowerlib.

[p-snft]

I think as an oemof project, it should also be located at https://github.com/oemof/hydropowerlib.
