  1. 1. The roles of transmission and distribution networks in integrating variable renewable electricity generation

    Författare :Joel Goop; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity generation; demand-side management; energy systems modelling; power systems; variable renewables;

    Sammanfattning : Emission reduction targets, together with other factors, such as security of supply, are driving the expansion of variable renewable energy sources for electricity generation, mainly solar and wind power. Trading across the transmission grid is an important measure to handle the increased variability and to balance supply with demand. LÄS MER

  2. 2. Impact of High Levels of Variable Renewable Energy on Power System Generation Adequacy : Methods for analyzing and ensuring the generation adequacy of modern, multi-area power systems

    Författare :Egill Tomasson; Lennart Söder; Dirk Van Hertem; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Generation adequacy; reliability; renewable energy; Monte Carlo simulation; electricity markets; optimization; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The generation adequacy of electricity supply has been an ongoing concern since the restructuring of the industry. Ensuring generation adequacy was a rather straightforward task in the era of natural monopolies. LÄS MER

  3. 3. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Författare :Joel Goop; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Sammanfattning : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. LÄS MER

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

    Författare :Anna Widerberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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. 5. Dampening variation in the European Wind Energy System

    Författare :Lina Reichenberg; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable renewables; electricity generation; geographic allocation; large-scale penetration of wind power; wind power;

    Sammanfattning : In a future European electricity system, wind power and other variable renewables may constitute a large share of electricity production. This prospect calls for measures to manage the inherent variability of wind power, such as demand-side management, storage, and flexibility of other generation. LÄS MER
