  1. 6. On stochastic optimization for short-term hydropower planning

    Författare :Yelena Vardanyan; Lennart Söder; Mikael Amelin; Afzal Siddiqui; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Renewable generation is the fastest growing energy resources in the past decade. Renewable energy sources, particularly wind power, provide clean and environmentally friendly energy to meet the system demand, meanwhile introducing huge levels of uncertainty in the system.

  3. 7. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

    Författare :Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. LÄS MER

  4. 8. Distribution Network Planning Considering Capacity Mechanisms and Flexibility

    Författare :Manuel Alvarez; Jin Zhong; Xiao-Ping Zhang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : The increasing penetration of distributed energy resources (DERs) has posed challenges to the distribution system operator (DSO) from the operation and regulatory point of view. High penetration of DERs could have negative impacts on the performance of the distribution grid, and depending on the regulatory framework, the DSO's remuneration as well. LÄS MER

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

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

    Sammanfattning : 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.

  7. 10. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Författare :Martin Biel; Mikael Johansson; Stein W. Wallace; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. LÄS MER
