  5. 3. 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

  6. 4. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation

    Author : Jimmy Ehnberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generation reliability; Isolated power systems; Wind power; Solar power; Renewable energy; Stochastic modelling;

    Abstract : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. READ MORE

  7. 5. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing

    Author : Piotr Lukaszewicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; Vehicle engineering; Farkostteknik;

    Abstract : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. READ MORE
