Modeling and identification of diesel-wind turbines systems for wind penetration assessmentModeling and identification of diesel-wind turbines systems for wind penetration assessment Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-141993enTo investigate transient performance problems and penetration limits, associated with the connection of wind turbines in isolated diesel supplied power systems, a computer program has been developed. The modeling of the main components of the system and the method used for the identification of the parameters of the diesel-generator units are described. Frequency and voltage variations obtained by the diesel units model are compared to experimentally obtained results. The computer program was applied to a typical diesel-wind turbine system of a small Greek island to investigate the impact of the connection or the parallel operation of the wind turbines on the frequency and voltage, as well as the transient stability of the system in case of short circuits in the networkhttp://creativecommons.org/licenses/by/4.0/IEEE Transactions on Power Systems381091 - 1097 Stavrakakis Georgios Σταυρακακης Γεωργιος M.P.Papadopoulos P.V Malatestas IEEE WECS (Wind energy conversion systems) wind energy conversion systems wecs wind energy conversion systems
