Assessment of the Impact of Dynamic Line Rating on Reliability Indices of Level I Systems

Background: This paper evaluates the impact of implementing dynamic line rating on the reliability indices of an electric power system. Methods: In order to obtain this goal, the implementation process of a dynamic rating model that considers the required variables for its functioning is built. A validation of the model is performed based on the measurements of an ASCR conductor in laboratory. Results: Subsequently, a reliability analysis that includes the use of the dynamic rating is structured and the impact on the reliability indices of dynamic rating within the electrical system is verified. Conclusion: In this way, it was possible to observe that considering dynamic rating on the transmission lines represents a positive impact on the reliability indices within the electric power system and allows the optimization of the use of existing infrastructure.
