  1. 11. Wind Power in Areas with Limited Export Capability

    Författare :Julija Matevosyan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; transmission capacity; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

    Sammanfattning : During the last two decades, increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. LÄS MER

  3. 12. Integration of Non-synchronous Generation - Frequency Dynamics

    Författare :Johan Björnstedt; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; Frequency dynamics; Frequency response; Non-synchronous generation; Power system; Synthetic inertia; Wind power;

    Sammanfattning : Traditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. LÄS MER

  4. 13. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

    Författare :David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

    Sammanfattning : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. LÄS MER

  5. 14. Impact of High levels of Wind Penetration on the Exercise of Market Power in the Multi-Area Systems

    Författare :Ekaterina Moiseeva; Mohammad Reza Hesamzadeh; Frank Anthony Wolak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind integration; market power; game theory; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : New European energy policies have set a goal of a high share of renewable energy in electricity markets. In the presence of high levels of renewable generation, and especially wind, there is more uncertainty in the supply. It is natural, that volatility in energy production induces the volatility in energy prices. LÄS MER

  7. 15. Wind Turbine Characterization by Voltage Source Converter Based Test Equipment

    Författare :Nicolas Espinoza; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grid Integration; Frequency Scan; Discrete Control; Wind Power; Grid Emulation; Voltage Source Converter VSC ; Grid Code; Low Voltage Ride Through LVRT ;

    Sammanfattning : In countries where wind power has become a relevant part of the total generated electrical power, transmission system operators (TSOs) have included in their Grid Codes specific technical requirements for interconnection of wind power plants. Some Grid Codes demand specific testing procedures in order to verify the fulfilment for their requirements. LÄS MER
