  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.

  5. 4. Load-current response to severe changes of voltage

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Shuhan Ma; [2017]
    Keywords : ;

    Abstract : Electric loads, such as computers, lamps, refrigerators and heaters connected to low-voltage distributionsystems in homes and offices differ widely in how their current responds to changes in the applied voltage.These voltage changes could be a total collapse of the voltage, a weak or strong reduction of amplitude,or a sudden phase-shift.

  6. 5. Organic-inorganic hybrid perovskites as light absorbing/hole conducting material in solar cells

    University essay from Fysikalisk kemi

    Author : Saman Ghanavi; [2013]
    Keywords : ;

    Abstract : Solar cells involving two different perovskites were manufactured and analyzed. The perovskites were (CH3NH3)PbI3 and (CH3NH3)SnI3. Both perovskites have a shared methyl ammonium group (MA) and are used as both light absorbing material and hole conducting material (HTM) in this project. READ MORE
