Uncertainty in the electric power industry
... time, the analysis emphasizes the need to include sufficient technical detail to account for the specificities of the electricity industry, notably the non-storability of electricity and the grid dependency. In ... Without them and the many fruitful discussions we had together the work would lack if not its essence then many of its flavors. My special thanks go to my father, D...
