  1. 1. Demand Side Activities for Electric Load Reduction

    Författare :Juozas Abaravicius; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Load demand; Energiforskning; Energy research; demand response; peak load reduction; load management; demand side;

    Sammanfattning : The research described in this thesis, focuses on some activities on the demand side that could reduce peak load in electricity system by using consumer flexibility i.e. by increasing the demand side response to signals coming from the energy market. LÄS MER

  3. 2. Modeling and forecasting the load in the future electricity grid : Spatial electric vehicle load modeling and residential load forecasting

    Författare :Mahmoud Shepero; Joakim Munkhammar; David Steen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; GIS; Photovoltaics; Residential Load Forecasting;

    Sammanfattning : The energy system is being transitioned to increase sustainability. This transition has been accelerated by the increased awareness about the adverse effects of the greenhouse gas (GHG) emissions into the atmosphere. The transition includes switching to electricity as the energy carrier in some sectors, e.g. LÄS MER

  4. 3. Dynamic Power System Load -Estimation of Parameters from Operational Data

    Författare :Ines Romero; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

    Sammanfattning : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. LÄS MER

  5. 4. Cognitive load in dialogue interpreting : Experience and directionality

    Författare :Aleksandra Adler; Elisabet Tiselius; Birgitta Englund Dimitrova; Christopher D. Mellinger; Agnieszka Chmiel; Stockholms universitet; []

    Sammanfattning : This dissertation investigates the effect of experience and language direction on cognitive load in dialogue interpreting. The general objective of the study is to contribute to a better understanding of cognitive processes involved in dialogue interpreting. LÄS MER

  7. 5. On the asperity point load mechanism for rolling contact fatigue

    Författare :Johan Dahlberg; Bo Alfredsson; Sören Sjöström; KTH; []
    Nyckelord :Rolling contact fatigue; Spalling; Asperity contact; Point load; Micro-cracks; Traction; Applied slip; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Rolling contact fatigue is a damage process that may arise in mechanical applications with repeated rolling contacts. Some examples are: gears; cams; bearings; rail/wheel contacts. The resulting damage is often visible with the naked eye as millimeter sized surface craters. LÄS MER
