  2. 1. Electricity across borders : regional cost sharing of grid investments, international benchmarking and the electricity demand of an ageing population

    Author : Hans Nylund; Andreas Stephan; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cost allocation; Game Theoy; Investments in Electricity grids; Efficiency benchmarking; Residential electricity demand; Economics; Nationalekonomi;

    Abstract : This thesis deals with issues related to investments and regulation of high-voltage electricity grids, and to the households’ demand for electricity. The thesis consists of four self-contained papers. Papers I and II address the challenge of reaching agreements on the expansions of electricity grid infrastructure across national borders.

  4. 2. Insights from modeling renewable electricity systems and developing hydropower models

    Author : Hanna Ek Fälth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

    Abstract : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. READ MORE

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

    Author : Quentin Ploussard; Luis Olmos; Andres Ramos; Efraim Centeno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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. READ MORE

  6. 4. Steady state analysis of HVDC grid with Wind Power Plants

    Author : Kalid Yunus; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
