Traditionally distribution networks have been predominately passive with electricity generated centrally flowing from the transmission system to customers connected to the lower voltage networks. However, with the growth of embedded generation at all voltage levels, and new smart technologies, Distribution Network Operators (DNOs) have the need to and, through Active Network Management (ANM) and the wider development of smart grids, the means by which to more actively manage flows on their networks. Unlike the DNOs, the Transmission System Operator (TSO) does manage the network in real time. ANM may nevertheless also have applications on the transmission network.
This Good Practice Guide for ANM has been commissioned by the Energy Networks Association’s ANM Working Group to consolidate learnings so far from the deployment of ANM schemes in Great Britain. The guide sets out current good practice for the commercial arrangements and technical deployment of ANM technologies, and is intended to be of use to a number of electricity system stakeholders, including the network operators themselves, customers, product manufacturers, regulators and policy makers. The guide also looks to the future, and how ANM may become more commonplace and the implications for future network systems operations.
There is to date no industry-agreed definition of ANM, but for the purposes of this guide, the following summary definition is used:
Using flexible network customers autonomously and in real-time to increase the utilisation of network assets without breaching operational limits, thereby reducing the need for reinforcement, speeding up connections and reducing costs.
