Case study of challenges and possible measures in the future Norwegian distribution grid
Challenge and objective
This case study aims to illustrate challenges and possible measures in a future Norwegian distribution grid in 2030-40. In line with official goals to decarbonize transport and increase the amount of distributed renewable power production, a future scenario is considered where the distribution grid is subject to considerable increase in PV production and EV charging.
Work performed
The case study is performed using the CINELDI MV reference grid and a 400V low voltage (LV) grid, building on tools and knowledge developed in CINELDI and affiliated research projects.
Significant results
Through simulations, it is shown how voltage violations, thermal overload and congestions can be mitigated by using a combination of active measures in the grid and flexibility resources. It is also shown how the electrical losses might be affected by PV production and EV charging, respectively.
Impact for distribution system innovation
The case study illustrates that challenges imposed to the distribution system by extensive increase in PV production and EV charging (in line with official goals related to meet climate targets), can be mitigated through active measures in the grid and by using flexibility, without grid reinforcements.
