    Sammanfattning : Two strong trends in society which may have a major impact on the electricity grid load in the near future are the expansion of micro production with solar cells, and the increasingly prominent role of electric cars in the automotive market. In this work, an attempt is made to develop standardized and not too time-consuming methods to study how different future scenarios with large-scale expansion of private micro production with solar cells, as well as a very proportion of cars are electric and being charged at home, affect the various parts of the network with regarding voltage levels and load rating.
