  1. 1. The role of location of low inertia in power systems

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Bashar Alahmad; [2021]
    Nyckelord :Low inertia; Frequency stability; Rotor-angle stability; Nordic 32; Kundur; PowerFactory; Small-signal stability; Inter-area oscillation; Rate of Change of Frequency.;

    Sammanfattning : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

  3. 2. Evaluation of Power Oscillation Damping in the Nordic Grid Using HVDC

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Hansson; [2020]
    Nyckelord :;

    Sammanfattning : 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).

  4. 3. Load Characteristic Influence on Power Oscillation Damping : Case Study on HVDC-interconnected AC-Grids

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Erik Björk; [2018]
    Nyckelord :;

    Sammanfattning : The increasing share of renewables in the electric grid may have a negative impact on the systemstability to which conventional control methods are insucient. The report focuses on the stabilityof low frequency inter-area modes. Along the development of renewables, power electronics aremore frequently used between the actual load and the grid. LÄS MER

  5. 4. An application of modal analysis in electric power systems to study inter-area oscillations

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektriska energisystem

    Författare :Francois Dussaud; [2015]
    Nyckelord :;

    Sammanfattning : In order to make the electricity supply more reliable and with the development of electricity trading, electric power systems have been steadily growing these last decades. The interconnection of formerly isolated networks has resulted in very large and complex power systems. LÄS MER
