The optimization is based on the ``pyomo=False`` setting in the :func:`network.lopf` and :func:`pypsa.linopf.ilopf` function. The optimization is based on the ``pyomo=False`` setting in the :func:`network.lopf` and :func:`pypsa.linopf.ilopf` function.
Additionally, some extra constraints specified in :mod:`prepare_network` are added. Additionally, some extra constraints specified in :mod:`prepare_network` are added.
Solving the network in multiple iterations is motivated through the dependence of transmission line capacities and impedances. Solving the network in multiple iterations is motivated through the dependence of transmission line capacities and impedances.
