Increasing of Dynamic Thermal Rating of Transmission Line

The thermal rating of transmission lines has been known for a long time that it is over designed. The rating can be increased through an application of dynamic thermal rating methods, which consider the real time state of each parameter rather than those of the worst case. The paper is focused the basic concepts for the dynamic thermal rating of transmission line, and considered how it is calculated and how it impacts to the system during operation. Finally, by considering of each parameter as random variable with an appropriated probability distribution, the obtained results from the proposed method have been shown.
