The Influence of Internal "Ex-ante Self-balancing" on the Operation of a Power System
2012 (English)Conference paper (Refereed)
Short-term variations in wind power generation make the real-time balancing of load and generation a more challenging task for the transmission system operator. Due to this, we explore the question whether ex-ante self-balancing can efficiently reduce the real-time balancing demand. Internal ex-ante self-balancing means that each power generating company tries to re-schedule its operation plan which it has committed itself to in order to balance it with the newest production forecast. This re-scheduling is done shortly before the period of delivery.
To assess its value, we evaluate possible trading decisions for power generating companies in different situations based on a hydro-thermal generation portfolio within the framework of the Nordic electricity market design.
