  3. 2. 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.

    Sammanfattning : Deploying wind power to a larger extent is one solution to reduce negative environmental impacts of electric power supply. However, various challenges are connected with increasing wind power penetration levels. LÄS MER

  5. 4. Impact of dependencies in risk assessments of power distribution systems

    Författare :Karin Alvehag; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning :  Society has become increasingly dependent on electricity, so power system reliability is of crucial importance. However, while underinvestment leads to an unacceptable number of power outages, overinvestment will result in costs that are too high for society. The challenge is to find a socioeconomically adequate level of risk. LÄS MER

  7. 5. Trade-offs and conflicting objectives of decision-making investments in low-carbon technology portfolios for sustainable development : National and continental insights offered by applying energy system models
