  1. 1. System impact of micro-production

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Annie Haraldsson; [2023]
    Keywords : Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

    Abstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG.

  3. 2. Reactive power management capabilities of Swedish sub-transmission and medium voltage level grid

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

    Author : Michal Tomaszewski; [2018]
    Keywords : electric power systems; reactive power; sub-transmission level grids; PSS E; power ow analysis; wind farms; smart grids; droop control; elektriska system; reaktiv eekt; mellan spanningsnivan; PSS E; strom odesanalys; vindkraftparker; smarta nat; droop control;

    Abstract : Rising penetration of renewable energy sources in electric power grids isboth a challenge and an opportunity to optimally utilize the potential of eitherwind or PV energy sources, to stabilize operation of future power systems.Bi-directional ows between distribution and transmission system operatorscause signicant problems with keeping the voltages in the grid within admissiblelimits.
