Overhead line rating forecasting for the integration of wind power in electricity markets

Wind power has a significant impact on the operation of electricity markets in areas with high penetration of wind power. As the electricity market is planned some hours in advance, it is necessary to forecast the wind power. Besides, wind power forecasting techniques can be adapted for the overhead line rating forecasting. This can be useful for defining advanced strategies for grid operation and improve the wind power integration. This paper analyzes the similarities and differences between the wind power forecasting and the overhead line rating forecasting. Some overhead line rating forecasting experiences are described and the preliminary results of a pilot project are shown.
