  2. 1. Combined Electrical Power Generation using Solar and Wind

    Author : Ingemar Mathiasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave length bands; atmospheric transmittance; energy storage; Wind turbine; wind speed; quantum dots; electrical load.; extinction coefficient; silicon solar cell; solar cell;

    Abstract : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. READ MORE

  4. 2. Analysis and Forecasting of Utility-Scale Hybrid Wind and PV Power Parks

    Author : Oskar Lindberg; David Lingfors; Joakim Munkhammar; Johan Arnqvist; Jakub Jurasz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-located; probabilistic; forecasting; trading; wind; solar; variability; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : The increasing share of wind and photovoltaic (PV) power in the electricity generation mix pose challenges in power system management due to their non-dispatchable and intermittent nature. Co-locating wind and PV parks, forming utility-scale hybrid power parks (HPPs), means that the sources can share grid connection, land, permitting procedures as well as operation and maintenance work.

  5. 3. The Polar Cusp and its Ionospheric footprint : Dynamics and Transients

    Author : Frédéric Pitout; Ryoichi Fujii; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Solar wind - magnetosphere - ionosphère interactions; polar ionosphere; Rymd- och plasmafysik; Space physics; Rymdfysik; Space Physics; rymdfysik;

    Abstract : The magnetopause, the boundary layer between the solar wind and the Earth’s magnetosphere, is not closed as we have long thought. Transfers of energy, particles and momentum from the solar wind to the magnetosphere actually take place. READ MORE

  6. 4. The raison d'être of diffusion intermediaries in solar and wind power in Sweden

    Author : Joakim Aspeteg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-intermediation activities; solar PV; value creation; wind power; adopters; raison d être; diffusion intermediaries; renewable energy technologies; innovation intermediaries; intermediation activities;

    Abstract : Renewable energy technologies such as solar photovoltaics (PV) and wind power are now mature enough to be utilized as a means to build a sustainable energy system. Regardless, the diffusion of these technologies is not always a seamless process since it involves many actors and complex implementation procedures. READ MORE

  7. 5. Variability and variation management in a renewable electricity system -large-scale wind- and solar power deployment in Europe

    Author : Lina Reichenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marginal cost of electricity; VRE; variability smoothing; solar power; power systems; renewable energy; wind power; energy systems modelling;

    Abstract : The large-scale deployment of wind and solar power poses challenges to the electricity system by introducing variability on the generation side. To handle these variations, variation management strategies can be employed to ensure that generation meets demand. READ MORE
