  1. 1. Parallel Operation of Grid-Forming Power Inverters

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

    Author : Alessia Camboni; [2023]
    Keywords : ;

    Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

  3. 2. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Leonardo Alvarez Urrutia; [2022]
    Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

  4. 3. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

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

    Author : Abdullah Albalali; [2022]
    Keywords : energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

    Abstract : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
