THE TRANSITION OF THE DANISH POWER SYSTEM FROM A FOSSIL FUELLED SYSTEM TO PRESENTLY HAVING 40% WIND PENETRATION

抄録

The paper deals with the transition of the Danish power system from a fossil fuel based system in 1990 to the present system with about 40 % wind power penetration. The paper describes the status of the system and the future targets. Weight is on explaining how this development has been possible while at the same time maintaining one of the highest security of supply levels in Europe. The key is flexibility provided by a strong internal transmission grid, strong interconnections to neighbors, well-functioning international markets, flexible generation units, market based system operation and integration across energy sectors.
