Flexibility Solutions in Distribution Networks
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.
- 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.
- 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.
