Dynamic (or real-time) thermal rating (which utilizes actual weather conditions in order to more accurately model electro-thermal coordination behaviour of high voltage conductors) promises to play a vital role in the planning of energy transmission of future smart power systems. This paper investigates the adequacy impacts of real-time line thermal ratings (of different underground distribution network...
Contemporary transmission networks are not fully utilized due to increased uncertainty and security buffers resulting mainly from the inefficient operation and planning, currently based on conservative predetermined thermal ratings. However, in a smart operation scheme, which considers time varying thermal ratings of transmission assets, operation and planning could be optimized to facilitate the...
Amid contemporary electric power system planning and operating regimes, the transmission network is pervasively operated, and planned, with time-invariant thermal ratings (TITRs) of transmission assets. This results in a transmission network which is not fully (and efficiently) utilized. In the future, however, power systems will be increasingly expected to transition into a smart grid—in order to...
Elevated temperature operation (ETO) is as an attractive way of enabling better utilization of existing transmission conductor assets especially during power system contingencies. However, due to the lack of Overhead Line conductor (OHLC) condition data, the present ETO ratings, short-term emergency (STE) and long-term emergency (LTE) ratings, are extremely conservative and inflexible. Furthermore,...
