Having made some important advances towards future offshore DC grids, a European Union-funded project that has trained the next-gen of offshore wind experts has just concluded. ‘MEDOW’ was an ‘Initial Training Network’ funded by the EU’s Marie Skłodowska-Curie Actions programme. It aimed to provide a ‘training through research’ approach to the exciting new field of multi-terminal DC grids for offshore wind power by appointing and training 17 promising young power systems engineers.
Renewable energy is essential for Europe to meet power demand and reduce carbon emissions. Offshore wind offers many advantages over other forms of renewable energy, including high yield of power and lack of disruption to landscapes or noise pollution. High Voltage Direct Current (HVDC) will be the key technology for integrating offshore wind power into AC (alternating current) main grids and for interconnecting European countries’ AC grids. HVDC transmission offers efficient transmission of large amounts of power over long distances. Development of DC transmission has gained significant momentum as a result of two key drivers. Firstly, the development of modern power conversion technology (voltage source converter) and secondly, the need for transmission of offshore wind power. Plans for the interconnection of multiple renewable power sources, loads and AC grids through DC technologies are leading to the exciting transmission concept of HVDC grids.
If Europe is to take advantage of the environmental and economic opportunities offered by offshore wind power, HVDC grids and of the significant potential for the creation of a European energy ‘Supergrid’, research expertise, both in the private sector and in universities and research institutes, must be developed. MEDOW was coordinated by Cardiff University, UK and consortium partners were:
The network also aimed to make meaningful research progress and generate new knowledge in DC grids and offshore wind power, building our network of people and organisations. Research activities and achievements include:
The consortium is due to sign a new grant agreement with the European Commission to run a second Marie Skłodowska-Curie Training Network, InnoDC, due to start in September 2017 and to offer another high quality training and development experience for promising young researchers in the field of offshore DC grids.
