To help you tell the difference between an AES and an LRIM we have provided definitions for our most commonly used acronyms, initialisms, specialist words and phrases below.
|AES - Advanced Encryption Standard|
|ANM - Active Network Management
The use of IT, automation and control to manage grid constraints associated with the integration of decentralised generation.
|AVC - Automatic Voltage Control
Automatic Voltage Control can monitor voltage levels in the distribution network and automatically adjust them within preset limits.
|CHP - Combined Heat and Power|
|DE - Decentralised energy
The generation of electricity through many small, localised energy sources. Also called dispersed or distributed generation (DG).
|DECC - Department of Energy and Climate Change
British government body
|DG - Distributed Generation
The generation of electricity through many small, localised energy sources. Also called dispersed or the generation of electricity through many small, localised energy sources. Also called dispersed or distributed generation (DG).
|DLR - Dynamic Line Rating
Dynamic Line Rating devices are used on the overhead electricity lines to calculate current carrying capacity in real time. For example, strong winds cool overhead lines increasing their current carrying capacity. Knowing the limits of a section of the network at any given moment will help the network operate at its maximum capacity.
|DNO - Distribution Network Operators|
|DOC - Directional Over‐Current|
|DPCR - Distribution Price Control Review|
|DSM - Demand side management
Also known as demand side response – the general action of managing energy demand, which includes overall efficiency measures to reduce consumption.
|DSO - Distribution System Operator
Distribution Network Operators (DNOs) are developing smart commercial arrangements and smart technologies to make the transitions to a Distribution System Operator.
|DSR - Demand side response
A direct response to a specific signal or request to reduce (or occasionally increase) energy demand/consumption.
|ENA - Energy Networks Association|
|EPRG - The University’s Electricity Policy Research Group
Based at the Judge Business School, University of Cambridge.
|EPSRC - Engineering and Physical Sciences Research Council
The main UK government agency for funding research and training in engineering and the physical sciences.
|ESS - Energy Storage System|
|EV - Electric vehicle
A car, van, truck, motorbike or scooter with a rechargeable battery, which uses electricity in place of petrol or diesel.
|FPP - Flexible Plug and Play|
|GB - Great Britain|
|Heat pumps - devices that extract heat from one source and transfer it to another at a much higher temperature. Used to heat (and also cool) buildings, swimming pools etc.|
|I&C - Industrial and Commercial|
|IEC - International Electrotechnical Commission|
|IET - Institution of Engineering and Technology|
|IFI - Innovation Funding Incentive|
|LCL - Low Carbon London|
|LCNF - Low Carbon Network Fund|
|Low Carbon Zone - one of the 10 London boroughs chosen by the Mayor of London to receive funding and support to reduce their carbon emissions by over 20% by 2012.|
|LRIM - Load Related Investment Model uses real 33kV network data and models specific demand and generation points. It also allows for different demand and generation growth scenarios to be evaluated.|
|LV - Low Voltage|
|Microgeneration - the small-scale generation of heat and power from a low-carbon source by individuals, small businesses and communities to meet their own needs. Includes solar and wind power systems.|
|ODS - Operational Data Store|
|Ofgem - The Office of Gas and Electricity Markets
Government regulator for the electricity and downstream natural gas markets in Great Britain.
|PV - Photovoltaic panels
Solar panels packaged together in cells to create electricity for commercial and residential use.
|Quadrature-booster - The Quadrature-booster is essentially two electricity transformers connected together at a specific point on the electricity network. They control or influence power flow by controlling phase angles between the three electrical phases of the electricity network. The Quadrature-booster is a mature technology and has been used by transmission companies like National Grid and across continental Europe since the 1970s.|
|RF - Radio Frequency|
|RIIO - Revenue = Incentives + Innovation + Output;
RIIO-ED1 will be the first electricity distribution price control review to reflect the new regulatory framework resulting from our RPI-X@20 review.
|RTU - Remote Terminal Unit|
|SCADA - Supervisory Control and Data Acquisition|
|SGS - balance schedules and coordinates electricity supply and demand on the grid by issuing advance schedules to meet a number of operational objectives, for example maximising renewable energy.|
|Smart Grid - Smart grids work together with smart meters. They will become the new electricity distribution network and will deliver low carbon electricity.|
|Smart Meters - electricity meters that record energy consumption in intervals of 30 minutes, monitoring the time of day at which most electricity is used and enabling users to tailor their consumption to times of day when there is less demand and therefore a cheaper tariff.|
|SNS - (Smarter Network Storage)
A Tier 2 LCNF project, aiming to prove the economic viability of energy storage on the distribution network.
|SOCS - Smart Optimisation and Control System
The communications platform between the energy storage system, the DNO control room and other electricity participants under the Tier 2 Smarter Network Storage project.
|SSN - Silver Spring Network|
|TSO - Transmission System Operator an organisation that transports energy such as gas or electricity on a national or regional level.|
|UK Low Carbon Transition Plan - the Department of Energy and Climate Change’s white paper setting out the UK’s first comprehensive low-carbon transition plan to 2020.|
|UKPN - UK Power Networks|
