  1. 11. Evaluation of Power Oscillation Damping in the Nordic Grid Using HVDC

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

    Author : Johan Hansson; [2020]
    Keywords : ;

    Abstract : With a rapid transition towards renewable energy sources and increasing demand for electricity, we are facing major changes in the electricity grid. With increased congestion and reduction of inertia the grid is becoming more sensitive to rotor angle stability issues, such as the stability of interarea modes or power oscillation damping (POD).

  3. 12. Dynamic Virtual Admittance Control Hardware-In-The-Loop Real-Time Simulation

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

    Author : Damien Gadou-Sanyal; [2020]
    Keywords : ;

    Abstract : To enhance the transient stability and the power oscillation damping of the powergrid, supplementary controllers can be applied to the embedded point-to-point High-Voltage Direct Current (HVDC) links. The work presented in this report aimed tovalidate the Dynamic Virtual Admittance Control (DVAC) designed in SuperGridInstitute, in Software- and Hardware-In-The-Loop (SIL and HIL) simulations.

  4. 13. Frequency Response from Inverter-Based Generation

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

    Author : Johanna Lindstén; [2020]
    Keywords : ;

    Abstract : The system inertia of the Nordic power system is expected decrease in the future. This is due to an expected reduction in synchronous generation from nuclear and thermal power. This will be compensated by an increase in power from inverter-based generation due to wind power’s expansion in the power system. READ MORE

  5. 14. Costly Remedial Actions Coordination

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

    Author : Quentin Willaime; [2019]
    Keywords : ;

    Abstract : The energy sector is evolving and the role of the Transmission System Operator (TSO)must adapt to these new changes. In fact, the energy transition modies both the natureof the production sources by integrating intermittent energies and the classical structureof the grid, going from a centralized topology to a distributed topology.

  6. 15. Detection and location of HVDC commutation faults from PMU data

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Alejandro Belinchon Calderon; [2018]
    Keywords : HVDC-links; HVDC converters; Commutation failures; Phasor measurement units PMUs ; Electric power systems; Wide Area Measurement systems WAMS ; Standard IEEEC 37.118; Single-line to ground faults; Three-Phase faults; Fault detection and location; Nordic 32; DigSilent-PowerFactory; PSCAD; MATLAB-Simulink; Symmetrical components.; Technology and Engineering;

    Abstract : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. READ MORE
