Use of day-ahead load forecasting for predicted cable rating

Abstract

In recent years, increasing attention has been placed on cable dynamic rating systems in an attempt to increase asset utilization and decrease constraint costs. In this work, the concept of Predicted Cable Rating system is introduced by building day-ahead load prediction into the dynamic rating system to perform day-ahead rating prediction. This allows the cable rating being calculated forward from any point within the next 24 hours. The method is applied to a cable tunnel system to investigate the likely errors in temperature prediction which may arise, with good performance being demonstrated.
