Uppsala Municipality is planning to build the southeast city district (SÖS), aiming to achieve climate neutrality by 2030 and climate positivity by 2050. In this thesis, the integration of electric vehicles (EVs) and charging infrastructure was investigated. It also examined the power demand, and the potential of photovoltaic (PV) production in combination with a battery storage system in SÖS, and its ability to reduce power peaks. The study was delimited to only incorporating charging demand in mobility houses, not from the private parking spots, as well as excluding alternative fossil-free vehicle options. Utilizing a stochastic model and data from Copenhagen and Stockholm, using trends for car pools and EV ratio, two scenarios were designed to forecast the spread of EVs and their impact on the power grid in SÖS by 2050. Since SÖS consists of both residential housing and workplaces, three different simulations were created to take their differences in mobility pattern into account. The two scenarios generated a different number of EVs, which resulted in a varied amount of charging points. Furthermore, the difference in EVs and mobility patterns showed different values of power demands and power peaks. PV panels combined with a battery storage system were able to both reduce the daily power demand, as well as the power peaks. For the sensitivity analysis, different sizes of the battery storage were examined. Finally, this report presents guidance for how to manage the challenges with an increased power demand from the more extensive use of EVs.
