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.

This paper describes the desktop modelling of a novel automation concept to traditional LV distribution networks based on the EA Technology "SignalSure" system, which is currently in operation on rail signalling circuits in the UK. EA Technology has carried out projects on behalf of a number of UK Distribution Network Operators through the Innovation Funding Initiative (IFI) to assess deployment options, technical constraints, benefits and safety implications. The findings from the project carried out for ScottishPower are presented in this paper.
