Elnätets beredskap inför en mycket storskalig utbyggnad av laddinfrastruktur i Sverige

Forecasts show a rapidly increasing amount of electric vehicles in Sweden. The purpose of this study was to examine the challenges with a large scale expansion of charging infrastructure for electric vehicles (EV) in Sweden. This was partially achieved by a survey, which was sent to the majority of the electricity distribution network operators (EDNO) and some other companies associated with the charging infrastructure in Sweden. The other part of the study examined how an increasing amount of electric vehicles, according to forecasts from year 2019-2030, in a smaller society would affect the local power grid and the local transformer. The result from the survey showed that many EDNO had a lack of knowledge about home charging which could delay or obstruct the transition to electrified transports. Also, regulations for EV charging were somewhat unclear or non-existent and almost no EDNO are planning for flexibility resources year 2030. The case study for the small society showed that the increasing amount of EV to 2030 will very much affect the total power load which puts new demands on the EDNO regarding dimensioning and control/digitalisation of the infrastructure. To succeed with the implementation of a large scale expansion of EV charge infrastructure in Sweden, the communication between different companies within the business field is of great importance.
