Sammendrag
This study presents a validation study of an approximated model of the European power system in 2014. A lightweight and open-source power-flow tool is used for this study. The tool and the model are publicly available and can be adapted to study future impact of large investments in the power system, specifically large-scale integration of renewable energy. The input dataset is based on a prior work, but it has been substantially updated for 2014. To maintain all aspects of the model open-source, only publicly available data was implemented. The modelling approach and simplifications are explained. Comparison of the simulation results with actual data on cross -border flows and energy mix for 2014 shows acceptable correlation. The model is able to capture main characteristics of the power system, such as reservoir handling, hydro pump pattern, and seasonal variation on cross -border flows.
