A constant equilibrium between power generation and consumption is needed to balance any electric system. Without an equilibrium the result will be frequency deviations and possibly system blackout. To prevent this the TSO manages a set of system services through reserve markets.
Renewable energy Hydropower
SINTEF PROMOTES EFFICIENT AND ENVIRONMENTALLY FRIENDLY ENERGY PRODUCTION FROM HYDROPOWER
Hydropower is by far the main source of electricity production in Norway today and will remain so in the future. SINTEF has extensive research expertise in hydropower.
The management of water and energy resources is practised by public authorities at municipal, regional and national levels. In special cases, clarification may be required in addition to what is usually needed in more normal management processes. There may be a need for the assistance of experts with special qualifications with regard to a certain method or issue, or with experience from the water system in question.
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.
Power systems and power markets in continental Europe are undergoing rapid growth. Nordic market players and system operators are currently facing key investment decisions linked to opportunities for enhanced flexibility in the production system (power output expansion and pumping) and an increase in the number of transmission cables serving Europe.
The environmental design of hydropower systems involves taking natural environment into account during power generation operations. The requirements of natural environment and the generation of electrical power are compatible provided we use the correct methods in planning, implementation and follow-up.
Fish ladders are constructed to enable fish to swim upstream past migration barriers. Such barriers may be natural or artificial and the aim is to provide the fish with access to areas which are important for their population development. It is important to understand the ecological challenges faced by the fish species in question as well as the technical systems which are relevant at an individual location. In regulated water systems it is also crucial to have knowledge of power station operation and of the challenges fish encounter when migrating downstream again past power station intakes and dams.
SINTEF Energy Research participates in projects in collaboration with a number of international research groups and hydropower industries. Our expertise regarding greenhouse gas processes in hydropower systems range from how the gases arise, via measurement and assessment to complete net accounting and potential methods for preventive measures.
Since the early 90's reservoirs have been identified as potential sources of greenhouse gas emissions to the atmosphere. At present, this field is not well enough established and our scientists work to gain a better understanding of the mechanisms and processes for greenhouse gas fluxes in regulated watersheds.
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.
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.
Self-healing electrical insulation materials for high voltage apparatuses are very attractive, especially for new and high-power demand applications when placed in locations which are difficult to access and in harsh environments. Applications include offshore wind farms, subsea grid and equipment located in the Arctic.
Smart Grid Laboratory
NTNU and SINTEF are building a new National Smart Grid Laboratory in Trondheim with funding from the Research Council of Norway in cooperation with the Artic University of Norway and Smart Innovation Østfold.
PRIBAS – Pricing Balancing Services in the Future Nordic Power Market
The Nordic power market is in transition, both in terms of technologies used for power generation and market structures.
LORCENIS – Long Lasting Reinforced Concrete for Energy Infrastructure under Severe Operating Conditions
The main goal of the LORCENIS project is to develop long lasting reinforced concrete for energy infrastructures under extreme operating conditions.
The main objective for the MonitorX project is to develop a model, and an additional software prototype, for optimal utilization of the lifetime of a component in a hydropower plant.
EMPS - multi area power-market simulator
EMPS (EFI's Multi-area Power-market Simulator) is a tool for forecasting and planning in electricity markets. It has been developed for optimization and simulation of hydrothermal power systems with a considerable share of hydro power. It takes into account transmission constraints and hydrological differences between major areas or regional subsystems.
ENKI - hydrological modelling framework
Enki is a hydrological modelling framework, originally designed as a R&D tool for building and evaluating distributed precipitation-runoff models. It is currently under operationalisation for everyday use in hydropower production. Enki is licensed as open source software under the GNU LGPL license, and is named after the Sumerian deity for water, intelligence and creation.
CEDREN: Environmental design
The concept of environmental design in regulated salmon rivers describes how to evaluate, develop and implement measures to improve living conditions for salmon populations in regulated rivers, while taking hydropower production into account. Watch our three minutes introduction film.
The role of fossil fuels and CCS in a cleaner transport system
In short, a possible solution for hydrogen production for cars could be to use fossil fuels. We will tell you why and how!
