  1. 11. Application of PSS to Improve the Stability of a Power System With a High Penetration of Renewable Energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sixten Norelius; Ylva Persson; [2023]
    Keywords : ;

    Abstract : Unlike traditional power generation composed of synchronous generators, renewable energy in theform of solar and wind power does not add inertia to power systems. Therefore, as increasedproportions of renewable energy are added, the dynamics of the power system will be affected. READ MORE

  2. 12. Mapping of IPM machine efficiency and Noise Vibration Harshness : An investigation into trade-offs with respect to efficiency and Noise Vibration Harshness

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Bix Eriksson; Erik Rudqvist; [2023]
    Keywords : ;

    Abstract : Due to the recent shift towards electrification, electric machines has become a prominent option to be used in vehicle applications. Much effort is spent in the development process of these machines to make optimizations in order to improve the performance aspects of the machine. READ MORE

  3. 13. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sophia Larbi Engelbrektsson; [2023]
    Keywords : Ancillary Services; Kinetic Energy; Frequency Dependent Load; Frequency Stability; Frequency Quality; KPI; Nordic Power System; Frekvensberoende Last; Frekvenskvalité; Frekvensstabilitet; Kinetisk Energi; Nordiska Elsystemet; Nyckeltal; Stödtjänster;

    Abstract : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

  4. 14. Study of vector control strategy on Interior Permanent Magnet Synchronous Motors

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Prabhu Bernard; [2023]
    Keywords : Direct Torque Control; IPMSM; implementation; performance;

    Abstract : This thesis presents a comprehensive study of Direct Torque Control (DTC) for Interior Permanent Magnet Synchronous Motors (IPMSMs) evaluating its potential in high performance motor drive systems. The research begins with a literature review, looking into the fundamental principles of DTC, Pulse Width Modulation (PWM), Space Vector Modulation (SVM) and Field Oriented Control (FOC). READ MORE
