Equivalent Distribution Networks for Power Systems - Grey-box Models for the Dynamic Behavior of Active Distribution Networks

The increasing number of renewable, converter coupled generation units within the distribution networks drastically impacts the behavior of electrical power systems. Due to the enormous number of distribution networks, a reduced and equivalent representation is required for large power systems to consider their dynamic behavior correctly. This thesis proposes different grey-box models for equivalent distribution networks, which are examined regarding their accuracy and robustness towards modification.
