Dynamic thermal rating for increasing network capacity and delaying network reinforcements

Currently the operators of electrical distribution networks face a number of challenges, such as load growth, the proliferation of distributed generation and ageing infrastructure. This is drawing attention to techniques which will allow more efficient asset utilisation and carefully selected reinforcement projects. This paper presents the findings of research into the technical challenges and potential benefits of dynamic thermal rating (DTR) systems. The adoption of DTR systems has the potential to improve network capacity and in some cases to offer an effective alternative to traditional reinforcement methods. The research presented in this paper suggests that, when compared to traditional solutions of network reinforcement, a DTR system can, in some cases, offer a less invasive and more cost effective solution which allows the DNO to realise improved network component utilisation.
