  1. 1. Efficient reduction techniques for a large-scale Transmission Expansion Planning problem

    Författare :Quentin Ploussard; Luis Olmos; Andres Ramos; Efraim Centeno; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; energy; electricity; transmission expansion planning; linear programming; integer linear programming; relaxation methods; clustering; dimension reduction; network theory graphs ; partitioning algorithms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of Transmission Expansion Planning (TEP) studies is to decide which, where, and when new grid elements should be built in order to minimize the total system cost. The lumpiness of the investment decisions, together with the large size of the problem, make the problem very hard to solve. LÄS MER

  2. 2. Power to the people : electricity demand and household behavior

    Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

    Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

  3. 3. Swedish industrial and energy supply measures in a European system perspective

    Författare :Louise Trygg; Björn G. Karlsson; Thomas B. Johansson; Linköpings universitet; []
    Nyckelord :Deregulated European Electricity market; Industries; Energy suppliers; CO2 emissions; Electricity reduction; European electricity prices; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A common electricity market in Europe will in all probability lead to a levelling out of the electricity price, which implies that Swedish consumers will face higher electricity prices with a European structure. This new market situation will force industry and energy suppliers to take new essential measures as actors in a deregulated European electricity market. LÄS MER

  4. 4. On Monte Carlo simulation and analysis of electricity markets

    Författare :Mikael Amelin; Lennart Söder; Hans Ravy; KTH; []
    Nyckelord :Electrical engineering; electricity markets; power systems; monte carlo simulation; Elektroteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This dissertation is about how Monte Carlo simulation can be used to analyse electricity markets. There are a wide range of applications for simulation; for example, players in the electricity market can use simulation to decide whether or not an investment can be expected to be profitable, and authorities can by means of simulation find out which consequences a certain market design can be expected to have on electricity prices, environmental impact, etc. LÄS MER

  5. 5. Demand Side Activities for Electric Load Reduction

    Författare :Juozas Abaravicius; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Load demand; Energiforskning; Energy research; demand response; peak load reduction; load management; demand side;

    Sammanfattning : The research described in this thesis, focuses on some activities on the demand side that could reduce peak load in electricity system by using consumer flexibility i.e. by increasing the demand side response to signals coming from the energy market. LÄS MER
