AMPACITY AND REGULATORY CHALLENGES FOR DLR ADOPTION FOR BETTER GRID USE IN WIND POWER TRANSMISSION

Abstract

A significant portion of the Brazilian transmission network is in regions characterized by strong winds, where wind farms are concentrated such as in the Northeast region of Brazil. The energy transmission capacity of said transmission lines is determined based on thermal limits, by technical standards for meteorological variables to limit the maximum current levels on the conductor. The cables of the electrical network installed in areas with high wind potential are susceptible to better cooling, creating opportunities for the analysis of mechanisms that can contribute to a better utilization of the transmission lines. This work presents a concise approach to the topic, exploring the window of regulatory opportunity for the use of dynamic ampacity calculation in segments of the Brazilian National Interconnected System.
