The (Python) code stored in the present Git repository implements two (toy) models both using PyPSA. These represent an exogenous-driven land transport and an endogenous-driven land transport. The main purpose of the (toy) models is to get familiar with PyPSA and energy system modelling in general. This familiarity will help enabling PyPSA-Eur-Sec with endogenous-driven land transport capabilities afterwards.
