Abstract
Denne afklaring baseres i Choice Awareness Theory for at fremstille forskellige valg i forbindelse med fremtidens mulige stigning i antallet af elbiler i Danmark. Ved hjælp af en model lavet i Excel, vil forskellige scenarier af den personlige elbil-bestand og type blive udforsket, både for distributions- og transmissionsnettet, i et forsøg på at besvare spørgsmålet om hvad der ville ske ved disse elnet, og om de ville holde til det øgede forbrug. Resultaterne peger mod at begge elnet er stærkere end forventet, men distributions-nettet er ikke velforberedt til at håndtere en stor mængde elbiler, hvor transmissionsnettet i stedet ikke ser ud til at komme til at opleve problemer. Modellen kunne udvides med industriel transport, eller finansielle overvejelser, for yderligere at udforske modellen. De negative resultater kan blive modvirket med et velforberedt elnet i begge tilfælde.
This thesis is based in Choice Awareness Theory in order to offer different choices in relation to the future prospect of increased EV power demand. Through the use of a custom made Excel model, different scenarios of residential EV population are explored, both for the distribution grid and the transmission grid in Denmark, in an attempt to answer the question of what would happen to these grids, and if they would break. The results point towards both grids being stronger than anticipated; but the distribution grid is ill-equipped to handle large volumes of EVs, although the transmission grid is unlikely to break at all as a result of increased EV population. Expansion of the model by way of commercial transportation or financial considerations might improve the accuracy of the results. The negative aspects of the findings can be countered by preparing the respective grids for the increased demand.
