EURECA, the Effects of Utilisation in Real-time on Electricity Capacity Assessments, investigates the operating regimes of thermal power plants in future generation portfolios with large amounts of variable renewable energy sources (VRE). The impacts of additional VRE and energy storage capacity on the operating profiles and flexibility of thermal power plans are investigated using a unit commitment and energy storage optimisation model.
MARINET, the Marine Renewables Infrastructure Network, is a network of research centres and organisations that are working together to accelerate the development of marine renewable energy technologies - wave, tidal and offshore-wind. It is co-financed by the European Commission specifically to enhance integration and utilisation of European marine renewable energy research infrastructures and expertise. MARINET offers periods of free-of-charge access to world-class R&D facilities & expertise and conducts joint activities in parallel to standardise testing improve testing capabilities and enhance training & networking.
Marine energy should make a substantial contribution to the UK renewable energy target of 30% electricity by 2020. Tidal stream turbines are a more mature technology than wave energy devices while the potential of wave energy is considerable. There is a growing capability and confidence in the loading and performance of marine energy devices in operating conditions as designs rapidly develop. However knowledge of extreme loading is less mature and indeed there is some uncertainty about their origin.
Funding (ca. £3m) has been secured from the European Regional Development Fund (ERDF), Scottish Government, Scottish Funding Council, Scottish Enterprise and ETP Member Universities to establish a Knowledge Exchange (KE) Network. This will catalyse and accelerate KE activity between academia and SMEs, thereby increasing innovation, advancing the development of the low carbon economy in Scotland and supporting Scotland, UK and the EU to meet ambitious 2020 low carbon targets.
This project is a collaboration between SuperGen Marine, the Exeter Centre for Water Resources (Non-SuperGen), Penn State University, Aquascientific Ltd., The Danish Hydraulics Research Institute and is mentored by Garrad Hassan partners. The primary goal is the introduction of a new hybrid optimisation approach that allows the multi-objective optimal design of the layout and power loadings of marine energy farms subject to environmental impacts. It involves a new, academically highly challenging integrated analytic/numerical/experimental, approach to optimising the performance of large tidal stream energy capture farms. The specific application focus involves tidal turbines suited to operating in shallow medium flow estuaries but the technique can be applied to all types of marine energy farms. Optimisation is subject to minimising flood risk, with further environmental impacts, such as sediment transport driven outcomes, being capable of subsequent incorporation as slow timescale effects. The work complements the PERAWAT project and has key partners in common.
Practical marine energy resources are subject to social and ecological constraints, such as conflict with other users of the sea and environmental protection. This research aims to contribute to a greater understanding of the practical constraints on marine energy developments, the extent to which they may limit the amount of power available for extraction and, most importantly, how energy production may be optimised within the limits set by these constraints.
