    Abstract

    As the deregulated environment of power systems has been spread in the world, it is essential to operate power systems efficiently and economy. Under the environments, with the advance of communication technologies and sensors, the so-called dynamic rating is now to be realized. The dynamic rating is a method which determines accurate ratings by utilizing real-time information such as conductor temperatures, ambient temperatures and wind speeds. The dynamic rating is considered to increase the thermal capacities of overhead transmission lines and therefore take on importance in the deregulated electric power industry. The importance of the dynamic rating lies mainly in the area of Available Transfer Capability (ATC) improvement. In this paper, the validity of the proposed dynamic rating application is shown from the viewpoint of ATC, especially, ATC with thermal constraints. In addition, the possibilities of ATC estimations using sensitivities are verified on the purpose of reducing calculating time, considering the importance of real time simulation of ATC.
