Tiivistelmä
Rapid development of electric vehicles could eventually expand to sparsely populated areas, where power loads are relatively low. A vast portion of rural distribution networks was built at the time when the expected power load was significantly lower than what the cumulation of modern electric appliances might require. Therefore, electric vehicle charging bears a potential risk to the distribution network systems in terms of reliable power flow.
The purpose of this thesis is to identify the most impactful electric vehicle charging related parameters. Several scenarios among the normal distribution curves on people's behavior were developed to analyze impact of each parameter. These scenarios were directed into a designed MATLAB model. Simulations depicted charging activity and identified charging load confidence intervals along with other desired results. Documented outcomes were afterwards compared to discuss whether it is possible to predict potential risks related to EV charging load given location, electric vehicle characteristics and people behavior.
