  1. 1. Entering renewable electricity production : An actor perspective

    Författare :Ingrid Mignon; Anna Bergek; Gunnel Sundberg; Harlad Rohracher; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Renewable electricity production; new entrants; energy transition; energy policy; innovation; entrepreneurship; institutional theory; innovation-­adoption; implementation;

    Sammanfattning : Although energy transition is considered one of the main challenges of our time, little attention has traditionally been paid to the actors participating in this transition, such as the producers of renewable electricity. Previous energy policy literature and policy- makers have assumed that these producers are incumbent actors of the current energy system, that is to say, large utilities producing both renewable and fossil-fueled electricity.

  3. 2. Power to gas : Bridging renewable electricity to the transport sector

    Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

    Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER

  4. 3. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

    Författare :Anna Widerberg; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

    Sammanfattning : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

  5. 4. Mathematical modelling and methodology for cost optimization of variable renewable electricity integration

    Författare :Caroline Granfeldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost optimization; variation management; variable renewable electricity; variable splitting; electricity system modelling; consensus algorithm; Lagrangian relaxation; wind power integration; long-term investment models;

    Sammanfattning : The global production of electricity contributes significantly to the release of carbon dioxide emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. LÄS MER

    Sammanfattning : This thesis investigates the role of different short-term electricity market design aspects that can facilitate better coordination of resources within the power system. The work also emphasizes on better cross-border integration of the short-term markets to improve the market liquidity, competition, social welfare, and flexibility in the system, which is essential for facilitating the integration of renewable sources.
