Bidding strategy optimisation in the electricity markets

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.

Decision support in energy and environmental management

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.

Distribution in the power system

The electrical power system is in a state of transition, and in future decades will be subject to far-reaching changes. New sources of production and patterns of consumption will result in power flow becoming more complex and dynamic, while the electrification of society at the same time places major demands on supply quality. The changes will be particularly great in the distribution grid, via which electricity is supplied to consumers. SINTEF carries out research in collaboration with electricity producers, grid operators and end-users with the aim of contributing towards the socio-economic development of a robust and environmentally-friendly power system.

Electric Vehicles / Mobile Storage

Transportation will be electric in the future. It can come from pure electric operating from batteries or via conversion of hydrogen in a fuel cell. Also hybrid solutions are a possibility. Transportation includes conventional passenger cars, heavy cargo, ships and railway. The battery in the vehicles can also be used as mobile storage which is connected to the electrical grid, e.g. if the car charges at home or is parked. This can help to reduce the negative effects to the grid, e.g. by (fast)charging of cars. New tariffs for both the extraction of energy and supply must come to deal with the future smart grid, including electric cars, solar, wind and advanced electrical equipment (consumer, market, grid).

Energy systems analysis

On the basis of our experience from developments in the Nordic energy market, which is one of the first efficient markets of its type, we provide analyses for a society in a constant state of change. We generate scenarios for a future Nordic and European energy system, taking the energy sector's "green" revolution into account. The scenarios are based on a large-scale integration of renewable energy sources and will enable our clients to achieve reductions in greenhouse gas emissions. This is the basis for identifying future challenges and for arriving at systems that will facilitate the achievement of an efficient and sustainable energy market, and energy systems, for the future.

Fish ladders

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.

Geothermal energy systems

Geothermal energy systems cover systems for both shallow and deep geothermal wells. Shallow geothermal boreholes, 50 - 200 m, are used as heat source or sink for heat pumping systems. Deep geothermal wells, typically 1-10 km, can retrieve heat with higher temperature. Heat with high temperature can be utilised directly, e.g. for district heating, or as a heat as source for running a heat-to-power cycle.

Hydrogen technology and energy storage

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.

Interaction DSO/TSO/customer

Today's limited operational interaction between DSOs and TSOs needs to be strengthened, due to, e.g., more variable distributed generation (DG) and regulatory requirements. In grids where the volume of DG is increasing, more active monitoring and control are required. The DSO's role is changing and its future role has to be clarified. The DSO/TSO interface requires, e.g., efficient information exchange and coordinated congestion management.

Market based handling of imbalances caused by renewable intermittent production

The increasing share of renewable energy (wind, solar) where the production is weather- and light-dependent, often called "intermittent" production, can create imbalances and major challenges for the Transmission System Operators (TSOs) who are responsible for the production/consumption balance and the system frequency quality.

Microgrids

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.

Multi-market planning

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.

Offshore wind operation and maintenance

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.

Smart Grids – from the drawing board to reality

Communication and interaction between components, systems, a diversity of organisations and consumers will be key factors in influencing tomorrow’s flexible energy system. In particular, the electrical power system will be subject to a radical increase in complexity. The result will be a dynamic system in which behaviour may be difficult or impossible to predict simply by studying individual components in isolation. In order to contribute towards addressing this situation efficiently, SINTEF is carrying out a series of system-based research projects, in which we are looking into how individual components or selected concepts function and respond when they interact. Our projects range from simulations, via laboratory experiments, to demonstration projects carried out in the power grid.

System analysis - development and operation

A main challenge in transmission system operation is to ensure optimal utilization of the existing power grid. Available transmission capacity is to a large extent determined from transfer limits on critical power transmission corridors. These transfer limits are usually determined from operational security considerations, taking into account critical contingencies and the risk of thermal overloads and stability problems.
