The Power Systems research team at Imperial made pivotal contributions in the design of power transmission networks, the equipment within these networks, and non-conventional electricity systems. Since 2008, the impact of their research has been to:
I1) influence government policies by contributing to House of Common Select Committee (2010);
I2) support the Fundamental Review of Supply Quality and Security Standards;
I3) assist National Grid in defining new investment affecting £3bn worth of network assets now approved by the regulator (2013);
I4) provide tools to develop the first offshore networks design standards in 2008, saving an estimated £500m by 2013 to date and a projected overall saving of £1-2bn by 2020;
I5) advance Alstom's design concept for next generation HVDC converter stations for offshore wind connection from TRL 1 in 2009 to TRL 4 in 2013 supported by 3 new patents;
I6) enable UK Power Network to plan network investment of £1.18bn and make savings of £130m (2013) through applying new technologies and demand response;
I7) facilitate a scheme for off-grid energy kiosks for electrification in rural Africa yielding social gains and a business opportunity.
Research at the University of Strathclyde between 2003 and 2008 directly produced the following impacts from 2008 onwards: 10 wind farms (17 MW aggregate capacity) connected to the Orkney power network from 2009 to 2013 with accompanying economic and environmental benefits; Orkney power network reinforcement deferral saving of £30M from 2009 with repeat deployments of Active Network Management (ANM) technology in other UK power networks; spin-out company formed in September 2008 with total revenues to date of £6.1M, equity investment totalling £3.5M and 35 FTE jobs created; provision of new power system options for long term network plans impacting the 2013 investment decisions in distribution network companies; contribution to the emerging Smart Grid business sector in the UK and overseas from 2008.
The energy regulator, Ofgem, drew on research from the University of Birmingham when it instructed the electricity industry to re-design transmission charges that recover £1.6 billion per year. This instruction, issued in May 2012, was the culmination of Project TransmiT which Ofgem launched in September 2010. As part of TransmiT, Ofgem commissioned three teams of academics to consider whether changes to transmission prices were desirable and, if so, to recommend changes. One of these teams was from the Universities of Birmingham and Strathclyde. The changes introduced by Ofgem — which aimed to send more accurate signals of the cost of dealing with low-carbon electricity — were those recommended by the Birmingham and Strathclyde team. As a consequence, the research has fundamentally shaped a significant change to the future of electricity pricing in Great Britain, affecting the costs incurred by the industry and the payments made by every consumer in the country.
Essex research has investigated a range of switching techniques to enable efficient routing in optical networks. This research informed the development of the iVX8000 system, the world's first `carrier class' converged switch and transport solution, launched in May 2011 by the network equipment manufacturer Intune Networks Ltd. The development, launch and field implementation of the iVX8000 system have underpinned a period of sustained growth and success for Intune. The company has enhanced its position within the photonics transmission sector and attracted €15M of venture capital and collaborative research funding since 2011.
This study is part of a research project on China's electricity industry conducted jointly with the Université de la Méditerranée in France, and Swiss Electricity Ltd, and is funded by the EU. Despite three decades of market-oriented reforms in China, the electricity price-formation process is still state-controlled. The study shows how this process induces electricity producers to manipulate costs to gain an advantage when negotiating prices with the state. Consequently, despite government intervention, industrial consumers in China pay as much as their counterparts in developed Western economies with liberalised electricity sectors. These findings have informed the latest plans for price reform being prepared by the electricity regulator in China.
Joint research by the Logistics Research Centre (LRC) and the Transport Research Laboratory Ltd directly influenced the government's decision in 2008 to allow which categories of longer and heavier vehicles (LHVs) onto UK roads. One category out of seven was recommended. This decision was informed by findings relating to impact on the railfreight business and road infrastructure. The LRC subsequently provided advice on cost/benefit of the excluded category (longer semi-trailers) which contributed to the government's decision in 2011 to undertake a ten year trial of 15.6m and 16.6m trailers on UK roads. In 2010-11 the LRC's research on double-deck vehicles was used by the UK government and Freight Transport Association as evidence for opposition to an EU proposal to limit trailer heights to four metres, a measure which would have imposed a significant economic and environmental penalty on the UK.
Prof Irving and Prof Sterling of the Institute of Power Systems at Brunel University collaborated with National Grid (NG) to develop and deploy a Sparse Dual Revised Simplex (SDRS), optimisation engine for real-time power allocation of all generators that were controlled by the NG. Since 2005-6 NG has been using the algorithms to aid in operation of their Balancing Mechanism, which provides a means of adjusting the level of production or consumption of individual generators or demands in the British Electricity Trading and Transmission Arrangements (BETTA). The algorithms enable the Balancing Mechanism (BM) to efficiently adjust outputs of generators in real time in order to balance the demand for electricity at minimum cost. Therefore, providing economic balancing of the transmission system at a scale of 2-3% of the £5bn annual electricity market (approximately £100M-200M per annum), hence about £800 million has been optimally traded in total in the BM since 2008. It is also important to acknowledge the reliability of the algorithms and SDRS optimisation engine from 2006 to present day, as periods of software outage carry high operational costs. The algorithms developed at Brunel continue to have very significant real world impact in terms of financial volume and its reach, such that every transmission scale power generator in the UK participates in the balancing mechanism and by implication every electricity-user benefits.
The supply of electrical energy to centres of demand is an increasingly important issue as our power generation sources decarbonise. Without innovation in our use of high voltage cables, security of supply to our major cities cannot be guaranteed. Our research has:
A series of funded research projects have been completed by the University of Sunderland in close collaboration with BT Research Labs Ipswich. This research, which has resulted in a series of novel optimisation approaches, led to the development of suite of tools used for network planning. These tools are primarily based upon the application of evolutionary computing methods. Researchers produced intelligent network planning tools for the development of the national Internet. The tools have been used extensively since 2008, and the network for the Olympic games in London 2012 was designed and planned using these smart tools. A company specialising in vehicle tracking has also been formed as a direct result of the research.
Pioneering research at Bangor on the advanced communications technology termed Optical Orthogonal Frequency Division Multiplexing (OOFDM) has enabled industrial impact with global implications. OOFDM was a candidate technique for the ITU-T G989.1 NG-PON2 and the IEEE 802.3bm standards and is currently under consideration by the IEEE 802.3 400Gb/s Ethernet Study Group. Supported by 8 patent families and first-phase funding of £1.1M, in 2013, the pre-revenue Bangor University spin-off company Smarterlight Limited, was established. Smarterlight has deployed services to several international telecommunications companies to develop advanced solutions for access optical networks and data centres.
