National Physical Laboratory
Measurement technology offers 839k tonnes of carbon savings and 250 million in economic benefit
New and improved technology for measuring power quality in smart grids could save 839k tonnes of carbon and bring 250 million annual GVA in economic benefit. The technology has been developed by scientists at the Centre for Carbon Measurement, part of the National Physical Laboratory (NPL), the UK's National Measurement Institute.
The growing complexity of the increasingly demanding and decentralised system for generating and distributing energy to homes and businesses creates many opportunities for power quality to be compromised. Smart Grids address this by managing and monitoring electricity throughout networks such as the National Grid. Electricity information is used to improve distribution and support integration of new power sources, such as renewables - where power generation is more volatile.
To minimise compromises, and maximise efficiency, real-time monitoring of power quality in the grid is essential. A technology developed by the Centre for Carbon Measurement provides one of the most accurate portable methods of making these measurements, and initial projects alone look set to produce huge carbon reductions.
The technology is a 'metrology grade' digitizer. It takes sample measurements of current and voltage using non-invasive techniques at about 25,000 times per second, and sends these measurements to an analogue to digital converter. It can then carry out real time maths using NPL developed algorithms to calculate various parameters relating to power quality.
These levels of accuracy were previously confined to the laboratory, but can now be made in the field. Measurements can be made at several points throughout the grid and compared.
The team that designed the digitiser used it to study power quality on one of the most challenging components of the Smart Grid a large scale photovoltaic array (PV) installation. The findings will enable grid planners to anticipate and sidestep several potential pitfalls in the design of the future grid and thus should make a highly significant contribution to carbon reduction.
An independent report by Technologia, a consultancy, calculated that the projected carbon savings from this project could be as much as 167k tonnes and would bring 50m of economic benefit each year from the retail value of the increased electricity output of solar cells.
The system is now being used in Belgium, Denmark and Turkey, helping scientists assess the impact of renewable electricity on the Smart Grid and plan for ambitious energy transmission schemes. Two more are being used in Sweden to monitor the power quality of a 255 kilometre submarine cable between Sweden and Poland.
If the impact of the five digitizers in use across Europe is comparable, as is suspected, the total annual benefits delivered would be 839k tonnes of carbon savings and up to 250 million GVA.
The digitiser was also shortlisted for a Climate Week Award earlier this month.
NPL is now planning to licence the proprietary digitiser design to a commercial instrument supplier which will massively expand the user base and greatly enhance its influence on the architecture and composition of the Smart Grids of the future.
NPL will be holding an event, Measurement to Enable Smart and Intelligent Grids, with the Royal Academy of Engineering the Energy Networks Association, on 1st May 2013. Details here: http://www.npl.co.uk/events/1-may-2013-measurement-to-enable-smart-and-intelligent-grids.

About the National Physical Laboratory
The National Physical Laboratory (NPL) is the UK's National Measurement Institute and one of the UK's leading science facilities and research centres. It is a world-leading centre of excellence in developing and applying the most accurate standards, science and technology available.
NPL occupies a unique position as the UK's National Measurement Institute and sits at the intersection between scientific discovery and real world application. Its expertise and original research have underpinned quality of life, innovation and competitiveness for UK citizens and business for more than a century.
About The Centre for Carbon Measurement
The Centre for Carbon Measurement will ensure the UK leads the world in emissions reductions and low carbon technology, and will firmly establish the UK as the financial centre of the global carbon market. The CCM is centred at The National Physical Laboratory (NPL), and works with partners across industry, academia and government.
The Centre focuses on three key areas: validating the claims of new green technologies; underpinning carbon trading and pricing; and developing accurate international standards for climate data measurement. This will inform policies for reducing and mitigating climate change, set international standards for carbon trading and reporting, and help commercialise low-carbon technologies.
