Wind turbines are continuously growing in size, and with the increasing focus on offshore installations, accurately analysis of wind loads and intermittency is of great importance.Windfarms typically consists of a large number of such turbines, and the wind interaction between the turbines must be known to be able to optimize the windfarm with respect to electricity production and to low maintenance cost. Such optimization strongly relies on the control systems used to operate the windfarm.
Renewable energy Wind power
SINTEF develops world-leading and innovative wind technology
Globally, wind power is the fastest growing energy technology. SINTEF is an international leader in research on offshore wind. Along with our partners, we are researching and developing innovative and cost-effective solutions for the future.
In a liberalised electricity market, such as is the case for the Nordic countries, electricity production levels and prices are determined via a market statement based on supply and demand bids provided by electricity producers and suppliers, and the major electricity consumers. In the case of electricity producers, an effective bidding strategy requires a thorough and comprehensive analysis of their own production systems, agreed market obligations, and forecasts of future developments in the power system.
The CFD group at SINTEF Energy Research has more than 30 years of experience in performing numerical modelling of chemically reactive processes in laminar and turbulent flows consisting of single-phase (gaseous fuels combustion) or multi-phase (solid fuels combustion) configurations. Depending on the specific needs and time constraints of our customers, we are able to perform numerical simulations that boast a wide range of accuracies, geometric complexity and computational cost.
High reliability of the electrical insulation system is of key importance to any high voltage apparatus. The effect of many parameters/mechanisms needs to be carefully assessed when designing electrical insulation systems. In particular the effect of humidity, temperature, pollution/contaminants, mechanical and electrical stress, and external pressure need to be assessed in order to assure high reliability of the insulation system.
Cooling is a crucial aspect of electronics design, all the way from high-power industrial applications to personal computers. We investigate and develop ways of creating more efficient and reliable cooling systems, using magnetic nanofluids (ferrofluids).
Hydrogen will be an important supplement to electricity as an energy carrier in future sustainable energy systems. In addition to being fuel for the transport sector, hydrogen will contribute to increased utilization of renewable energy sources. The need for energy storage will increase dramatically, and hydrogen will be the preferred option for large amounts of energy, and storage over longer periods.
Wind turbines and their components are subjected to large long lasting loads and harsh environment resulting in high demands to the applied structural materials and protective coatings used. SINTEF Materials and Chemistry works on development, testing and modelling of a wide range of materials applied in wind turbines.
A self-sustaining and secure energy system is one of the main pillars of future society. The energy system (generation, transmission, demand) will become more decentralised with production taking place closer to customers and involving technologies such as solar panels, fuel cells, micro-turbines, storage and combined heat and power systems.
The spot market is by far the largest market for the physical supply of electrical power. The spot market is a day-ahead market, but there are also markets that trade on an intra-day basis for the supply of reserves and balancing power, and for trading in bilateral contracts. The intention is that, within the electrical power system, trading in all these markets shall be linked together as part of the same production and transmission system. This requires multi-market planning.
Electricity from offshore wind farms can replace generation from fossil sources and will be an important part of a sustainable future energy system. It represents a golden opportunity to create new knowledge-based jobs and fuel a “green transition”.
Operation and maintenance costs constitute to a significant part of the total costs of offshore wind power. Therefore, the development of improved and new solutions for operation and maintenance (O&M) of offshore wind turbines and wind farms is an important contribution to make offshore wind power more cost-effective. SINTEF Energy Research has developed models and tools for optimizing O&M and has competence on inspection and condition monitoring of wind turbine components, especially electrical components, and components in the wind park's grid connection.
The conversion of electric power by means of power electronics (converters) is playing an increasingly important role in various parts of the power system. Examples include the integration of renewable power plants, high-voltage direct current (HVDC) transmission and electrification of the oil and gas sector.
A power transformer is a complex apparatus with windings, core, tap-changer, bushings etc., designed and manufactured for many years of operation in a power system. SINTEF has know-how and runs projects in the transformer technology field; spanning from development and testing of materials for manufacturers, ageing performance, condition monitoring and life estimation, to analysis of interaction between power systems and transformers. A big challenge for the utilities is asset management of ageing transformer fleets.
NOWITECH - Norwegian Research Centre for Offshore Wind Technology
NOWITECH (Norwegian Research Centre for Offshore Wind Technology) is one of eight research centres for renewable energy appointed in february 2009.
LEANWIND - Logistic efficiencies and naval architecture for wind installations with novel developments
This project seeks to apply lean principles to the offshore wind farm project lifecycle. The primary LEANWIND objective is to provide cost reductions across the offshore wind farm lifecycle and supply chain through the application of lean principles and the development of state-of-the-art technologies and tools.
