  1. 1. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

  2. 2. Interharmonic Analysis of Sustainable Energy Sources and Loads : Comparing two signal processing methods for estimation of interharmonics
