N2 - This paper analyzes innovative devices tooptimize the energy flows transmission on existing overheadlines. Indeed sometimes the structural asset isn’t adequateto manage energy generated by Renewable Energy Source(RES) in particular operating conditions. In addiction theoutage of primary substations on the grid and the increaseof consumptions have caused growing load currents. Inorder to satisfy these needs, TSOs have adopted newmeasures on existing power lines and N-1 criteria to ensuresthe electrical grid security. These particular devices areDynamic Rating systems. After introducing thermalresistant conductors and Dynamic Rating (DR) solutions,paper reports two different applications used by TERNAItalian TSO. These systems are already installed on linesand they are contributing to increase power flows thanks toraise by 10-30% of the real time dynamic ratings than thestatic evaluations. Advantages for electrical systems aremany such energy vectors optimizations, congestionsreductions, reliability increasing, cross-border power flowsincreasing, smart grid development.
