“…Reference [13] discussed the real-time monitoring of the conductor's conditions and its importance for assessing the real-time rating. In addition, a DTR system was presented in [14] which uses real-time weather information for the optimization of transmission path utilization under N-1 contingency conditions. Moreover, DTR models and monitoring by means of different equipment were discussed in [15].…”

Dynamic thermal rating (DTR) of transmission system facilities is a way to maximally realize the equipment capacities while not threatening their health. With regards to transmission lines, the allowable current of conductors is forecasted based on the environmental situations expected in some forthcoming time periods. Due to the fact that weather conditions continuously vary, sampling points are very limited against many line spans, and the measurements have an inherent error, uncertainties must be appropriately included in the DTR determination. This paper adopts the fuzzy theory as a strong and simple tool to model uncertainties in the DTR calculation. Since DTR intends to determine the line capacity for some periods ahead, the capability of fuzzy computation in predicting future phenomena is very fruitful here. In the proposed model, variables, such as ambient temperature, wind speed, wind direction, and solar hour angle are assumed to be fuzzy numbers. Numerical simulations are provided based on inputs taken from real databases and reasonable assumptions as well. The results obtained support the validation and efficiency of the proposed model.

“…Dynamic Line Rating (DLR), on the other hand, can increase the efficiency and the reliability of power sys-tems. The dynamic line rating is one of the new practices in power transmission net-work and calculates the thermal capacity of lines based on the real-time line condition and surrounding ambient factors (Ciniglio and Deb 2004, TWENTIES (Transmission system operation with large penetration of Wind and other renewable Electricity sources in Networks by means of innova-tive Tools and Integrated Energy Solutions) 2013). Technologies developed for dynam-ic line rating and real-time monitoring are reviewed in the literature (Fernandez, E., Albizu, I., Bedialauneta, M.T., Mazon, A.J., Leite, P.T.…”

Due to increase in electricity demand and renewable resources penetration, power transmission infrastructure is utilized close to its technical limits. Dynamic line rating is one of the new practices in power transmission management by which existing transmission lines can be more eﬃciently utilized. In the literature, dynamic rating is usually applied to all lines of the power system which is not desirable as it is risky to simultaneously monitor a high number of transmission lines. In this paper we propose to apply dynamic rating on few and most suitable lines to eﬀectively increase the system N–K reliability. We develop a robust min-max-min three-layer optimization model to find minimum number of lines for dynamic rating. We use duality theory and convert the three-layer problem into a two-layer min-max problem and then we develop a benders decomposition framework to solve the two-layer problem. We use two test power systems to demonstrate our solution approach and analyze the results.
