  3. 2. Small Signal Stability of Power Systems With Increased Converter Based Power Production

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

    Author : Gustav Kjellson; Josefin Gustafsson; [2022]
    Keywords : Small signal stability; Power system stabilizer; Renewable energy; Grid following converters; Grid forming converters;

    Abstract : The aim of this project is to analyze how increasing the share of converter-based power production in a power system affects the small signal stability. The project also aims to stabilize systems using Power System Stabilizers (PSSs), and examine the effect of two different types of power electronic converters: grid following (GFL) and grid forming (GFM).
