  2. 1. Stochastic Modeling and Optimization under Uncertainty of a Hydro Power System

    Author : Roger Halldin; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; programming; operations research; Statistics; energy derivatives; multistage stochastic programs; electricity prices; principal component analysis; Scenario trees; inflow modeling; operationsanalys; programmering; aktuariematematik;

    Abstract : Electricity bought and sold on the deregulated Nordic power market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. The inflows to these reservoirs show a yearly cycle and seasonal planning of the production is necessary. Seasonal planning up to 1. READ MORE

  4. 2. Scenario trees for inflow modelling in stochastic optimisation for energy planning

    Author : Roger Halldin; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Nordic countries Norway, Sweden, Finland and Denmark have formed a deregulated power market. Electricity bought and sold on this market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. READ MORE

  5. 3. Robust Energy Systems. Strategies for CO2 Emission Control

    Author : Tomas Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; No Hedging; scenario analysis; IEA-MARKAL; energy planning; Hedging; carbon dioxide;

    Abstract : This dissertation deals with strategies to handle uncertainty about restrictions in CO2 emissions. A method has been developed for treating sequential decisions in energy planning. The method is an extension of the conventional scenario analysis, and is based on the evaluation of decision trees. READ MORE

  6. 4. Do forests have an impact on water availability? : Assessing the effects of heterogeneous land use on streamflow in two monsoonal river basins

    Author : Julie Wilk; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The aim of this thesis is to assess the effects of land use changes on streamflow in two river basins, the upper Bhavani in south India and the upper Nam Pang in northeast Thailand. In the Nam Pang basin, the forest cover has decreased from 80% to 27% in the last 30 years. Despite this, almost no changes in streamflow patterns or amountswere found. READ MORE

  7. 5. Optimal regulating power market bidding strategies in hydropower systems

    Author : Magnus Olsson; Lennart Söder; Terje Gjengedal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electricity market; stochastic optimization; bidding strategy; time series analysis; Electrical engineering; Elektroteknik;

    Abstract : Unforeseen changes in production or consumption in power systems lead to changes in grid frequency. This can cause damages to the system, or to frequency sensitive equipment at the consumers. The system operator (SO) is the responsible for balancing production and consumption in the system.
