The medium-voltage grid, which is almost 40,000 kilometers long, is an important part of Alliander's electricity grid. The pressure on this part of the grid is increasing uncontrollably, due to the increase in the amount of PVs, electric vehicles and heat pumps, amongst other things. A major challenge for Alliander is that very few measurements are available in this part of the grid, and the measurements that are present are usually only current measurements that cannot determine the direction of the energy flow. It is therefore often difficult to determine exactly how much room there is left for new customers at a certain spot.
To cope with this challenge, many analytical, statistical and machine learning methods are applied for power system analysis, which usually requires power system calculations (preferably in parallel) for a substantial number of simulation cases/scenarios.
