Short summary
The paper applies portfolio selection methodology to the problem of allocating offshore wind farm resources to various potential wind farm regions in Norway. The allocation aims to achieve high and stable wind power production under various constraints. Spreading the wind farms geographically has a large impact on the stability of the portfolio in terms of variance, and the results are consistent for the two sets of candidate regions studied. Sequential selection gives a good solution.
