starting point is a new installation of oemof.solph v.0.4.1. The basic example runs with the preset time steps without any problems. However, if you increase the time steps, the problem arises that at the step model = solph.Model(energysystem) the program takes a very long time for the calculation. With 24751 time steps (nearly 1 year) it takes approx. 10 h. In addition, the calculation runs only on one cpu (same issue on two different computers and venvs). Beyond that, the solver (CBC) does not find a solution.
The question: what could be the reason that the initialization of the model takes so long? Is there a way to speed up the step here? Is it possible to set the program to run on more than one cpu? Can this problem be caused by the oemof version 0.4.1? This problem did not occur with version 0.2.3.
Some hints to solve the problem would be great!
