The impact of home charging of electrical vehicles at Falun's low-voltage distribution grid (English)
Abstract [en]

The number of electrical vehicles in Sweden are increasing faster for every year and the demand of charging them at home is growing as well. This requires high delivery reliability and a stable low-voltage distribution grid. In this master thesis three different low-voltage networks are modelled and simulated together with load which corresponds home charging of electrical vehicles (EV) to analyse if the grid is able to handle these kinds of stresses. Information of the different grids were gathered from Falu Energi & Vatten and modelled in Matlab together with EV charging loads generated in a separate program. The electricity consumption data used in the simulations were measured at the transformer in each grid. A regression analysis of the consumption data were preformed to calculate values which corresponds to a worst case scenario. The results show that the low-voltage distribution grid in Falun is well dimensioned and can handle these possible future loads even in the worst constructed scenario.
