      Innovative tools for offshore wind and DC grids​

       

      InnoDC (Innovative tools for offshore wind and DC grids) is a European Training Network (ETN) funded by the European Union’s Horizon 2020 Marie Skłodowska-Curie Actions (MSCA) programme. ETNs provide training through doctoral research to talented early stage researchers (ESRs).

      InnoDC ESRs will enrol on PhD degree programmes and be employed for 36 months in a network of universities and industry with expertise in offshore wind power generation and supply. Through the individual ESR research projects, InnoDC will address the technical challenges linked to the development of offshore grids and hybrid AC/DC systems.

      We’re looking to appoint and train 15 promising early career researchers in a network of universities and companies active in research into offshore wind power. ESRs will study for PhD degrees, receive wide-ranging technical and personal skills training and disseminate and communicate their work to a wide range of people.


      MEDOW has received funding from the People programme of the Seventh Framework Programme of the European Union.

       

      The MEDOW consortium is made up of eleven partners (five universities and six industrial organisations). Each institution in the consortium contributes various expertise on the manufacturing, design, operation, and control of multi-terminal DC grids.

       

      A DC grid based on multi-terminal voltage-source converter is a newly emerging technology, which is particularly suitable for the connection of offshore wind farms.  Multi-terminal DC grids will be the key technology for the European offshore ‘supergrid’.

       

      This project will recruit twelve early-stage researchers (ESRs) and five experienced researchers (ERs).  In addition to their individual scientific projects, all fellows will benefit from further interdisciplinary and intersectoral education, which includes internships and secondments, a variety of training modules as well as transferable skills courses and active participation in workshops and conferences.

       

      MEDOW offers a development path to researchers across Europe in the area of DC grids, in addition to fostering greater ties between industry and academia in this key development area.

       

      The project will also host a number of outreach activities which will aim to create awareness among the general public about the research work carried out by the project and its implications for citizens, as well as to introduce school and university students to science, research and innovation.

       

      The project is co-ordinated by Cardiff University (UK).

      The BEST PATHS project will help to overcome the challenges of integrating renewable energies into Europe’s energy mix.

       

      With nearly 40 leading organisations from research, industry, utilities, and transmission systems operators, the project aims to develop novel network technologies to increase the pan-European transmission network capacity and electricity system flexibility. A budget of 63 million Euros that will be 56% co-funded by the European Commission under the 7th Framework Programme for Research, Technological Development and Demonstration

      Mitigating the effect of low inertia and low short-circuit level in HVDC-rich AC grids

      Renewable power, particularly offshore wind power, will be a major element of the UK's transition to meet its energy demands while reducing carbon emissions. HVDC will be the key technology for integrating offshore wind power into the UK AC grid and for interconnecting other AC grids in Europe. Line commutated converter (LCC) HVDC is particularly suitable for bulk power transfer while voltage source converter (VSC) HVDC is particularly suitable for connecting offshore power into AC grids with low inertia and low short-circuit level. Multi-terminal HVDC networks and DC grids based on VSC technology will be developed across the North Sea to form a future SuperGrid to increase the flexibility, redundancy and economic viability of offshore wind power transmission.

      Through this project, in-depth understanding of operation characteristics of AC grids which are rich in HVDC links will be achieved. Solutions will be founded to enhance the system inertia and short-circuit level. More renewable power through HVDC can be integrated into AC grids without deteriorate the system performance. The research outputs of this project will be disseminated through industrial partners, international academic associations, conferences and journal publications.

      Application of dc circuit-breakers in dc grids

      The European Union Renewable Energy Directive has committed the Member States to National targets for renewable energy production such that at least 20% of the EU’s energy will be produced from renewable sources by 2020. Meanwhile, the creation of an internal market for energy remains one of the EU’s priority objectives. The development of an interconnected internal market will facilitate cross-border exchanges in electricity and improve competition. The potential role of HVDC in integrating renewable energy generation and cross-border electricity exchanges is widely recognised and many ideas for DC grids linking the transmission systems of different countries and renewable generation are being promoted.

      At present, no DC circuit-breaker is commercially available and any DC fault will affect the entire DC network. A DC grid is, therefore, restricted to a single protection zone at present and the capacity of generation connected to it may not exceed the infrequent infeed loss risk limit prescribed by the Security and Quality of Supply Standard (SQSS). The DC circuit-breaker is therefore an essential technology enabling the concept of a DC grid to develop.

      Enhanced Renewable Integration through Flexible Transmission Options

      (EPSRC UK-China )

       

      China is installing wind farms faster than any other nation and the UK is leading deployment of offshore wind farms. Both nations will face challenges in connecting renewable sources in remote areas over (electrically) long cable or overhead DC routes and also challenges in controlling a system with a high proportion of asynchronous generation. This proposal identifies areas of common technical challenge and lays out a joint programme to analyse the issues and assess possible solutions.
      The key outputs will be the analysis methods that are developed to assess the problems identified (and which are useful to grid system operators); proposals for engineering solutions (useful to system operators and equipment vendors) and verification of these proposals through scaled laboratory test systems and real-time simulation.
