Challenge and objective

  • The power system is currently facing challenges regarding increasing electrification, the integration of variable renewable energy (VRE), and the growth of distributed energy resources (DER).
  • Flexibility in the power grid is seen as an important part in overcoming these challenges.

Work performed

  • Analysis of the potential and need for flexibility in the distribution grid on the island of Utsira.
  • Scenarios show how increased electrification will cause significant voltage variations in the grid.
  • Scenarios including flexibility solutions, demonstrate a positive impact on grid conditions.

Significant results

  • High Demand Side Response(DSR) rate for smart charging of EVs will reduce voltage variations.
  • Load shifting with BESS* for charging the planned electric ferry will reduce voltage variations and reduce needed grid reinforcements.
  • The load increase due to EVs will demand an increase of power supply from the VRES.
  • The flexibility potential in thermal loads is not suffi-cient to cover predicted increase in power demand.

Impact for distribution system innovation

  • Knowledge about how flexibility can be used to cope with the expected electrification.
