Abstract :
Increased utilization of transmission critical path by wide area real time dynamic rating using Internet based weather data is presented. Economic analysis shows significant benefit of operating transmission lines at higher ratings by taking advantage of favorable weather conditions during overload conditions. A new line current profile based dynamic line rating system has been implemented at Idaho power by real time exchange of data with energy management system. A case study of an internal transmission interface comprising the Brownlee east path in Idaho power using the new dynamic line rating system and an associated overload mitigation system is presented. It is shown there is minimum risk of overloading a circuit by increased transmission path utilization under N-1 contingency conditions.
