Lågspänningsnätets kapacitet för laddning av elbilar. : En studie om lågspänningsnätets kapacitet med avseende på elbilsladdning.

Sammanfattning: The power grid companies must now review how to meet the increasing electrification in society. This report examines how the local low-voltage network in Karlstad will cope with an increased proportion of electric car charging in the home. With help from hourly measured values and high-resolution measured values, it is desired to study this. This study is intended to serve as a basis for future network planning and investments. By comparing measurements with different resolution and historical measurements, the load that electric car charging can cause on the grid is studied. The results show that the grid has the opportunity to meet the expected load. Problems can occur with 100% EV penetration, but with the help of support services and adjustments of the tariffs, a postponement of a grid expansion is possible.
