Case studies on impacts of plug-in vehicle charging load on the planning of urban electricity distribution networks

摘要

In this paper, the impact of plug-in vehicle charging load on electricity network planning is investigated by means of case studies which are based on statistical PHEV charging load modeling work and co-operation with two Finnish distribution network companies. According to the case studies, the impacts of plug-in vehicle charging load on Finnish urban distribution networks are modest with low penetration levels, but with high penetration levels plug-in vehicles should be taken into account in long-term network planning. Also, needs and possibilities of “smart charging” were acknowledged from the calculation results.
