Deployment of Active Network Management technologies in the UK and their impact on the planning and design of distribution networks

Distribution networks in the UK, as in other developed countries, were designed to operate passively and deliver unidirectional power flows to dispersed end users. The introduction of distributed generation (DG) can render the existing operational philosophy invalid. Active network management (ANM) solutions are being developed to enable the increased connection of DG, often on a case by case basis as an economically preferable alternative to network reinforcement. A recent study undertaken by the University of Strathclyde has updated a register of completed and ongoing active management pilots, trials, research, development and demonstration activities. By considering the type and technical focus of each activity, the register demonstrates technical areas where much focus has been directed to date, where solutions have been implemented and where solutions are only now emerging. For solutions which have been implemented, the register provides an overview of the scale and impact of the activity, making the register a valuable resource for network planners. Analysis of the register content provides a snapshot of the current state of ANM, and provides recommendations to the key parties involved in the development and deployment of ANM solutions and technologies.
