The effect of large-scale wind power on system balancing in Northern Europe

Summary form only given. The on-going development in the electrical system and the transition from a mainly thermal dominated power system into a system, widely affected by renewable production resources, requires a revision of future balancing strategies facilitating the secure integration of renewable energy. Especially the increasing wind power penetration with its uncertain production on all time scales will largely affect the system operation, requiring a higher flexibility and thus more reserve capacity providing balancing energy.
