  1. 21. Steady state analysis of HVDC grid with Wind Power Plants

    Författare :Kalid Yunus; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ARIMA; electricity price; meshed HVDC grid; WPP; transmission tariff; temporal and spatial correlation; electricity market; VSC HVDC; wind speed modelling; secondary supervisory controller; LRMC; SRMC; PV; primary controller; investment cost;

    Sammanfattning : The idea of building a multi-terminal, even a meshed HVDC grid in the North Sea, that can inter-connect surrounding nations, is being discussed widely. Such a system is expected to be realised in steps through the interconnection of wind power plants and electricity markets. LÄS MER

  3. 22. Energy Services in Sweden - Customer Relations towards Increased Sustainability

    Författare :Kerstin Sernhed; Energihushållning; []
    Nyckelord :demand-side management; district heating; electricity; Customer relations; district-heating marketing strategies; load management; feedback;

    Sammanfattning : Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill.

  4. 23. Distributed Resources in a Re-Regulated Market Environment

    Författare :Thomas Ackermann; KTH; []
    Nyckelord :Distributed Generation; Electricity Markets; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis analyses the value that distributed resources(DR) can contribute to an economically effcient operation of are-regulated electricity market and discusses the relevantchanges in the regulatory framework to allow the appropriatedevelopment of DR whenever DR may increase the economiceffciency of the electricity market. Distributed resources thereby combine two aspects:Distributed generation and demand-side resources. LÄS MER

  5. 24. Aspects of Energy Resource Management

    Författare :Tomas Kåberger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bio-energy; value; interdisciplinary; life-cycle analysis; tax-shift; resource; energy; electricity;

    Sammanfattning : Energy resource management requires input from many disciplines. The three first papers in this thesis deals with the use of physical terms in the interdisciplinary process where inputs from different disciplines are handled together. LÄS MER

  7. 25. 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 :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
