Impact of increased wind power production on power system security

Ovaj diplomski rad bavi se modeliranjem dijela elektroenergetske mreže unutar kojeg su uz postojeću vjetroelektranu priključene još dvije nove. Cijeli model promatranog sustava je napravljen u programskom paketu ETAP. Praćene su promjene tokova snaga ovisno o tipu generatora u ispitnoj vjetroelektrani (sinkroni, asinkroni, dvostrano napajani asinkroni) dok su nove elektrane modelirane dvostrano napajanim asinkronim generatorima. Također, ovisno o ispadima pojedinih elemenata mreže ispitivan je kriterij sigurnosti (n-1) za sva tri tipa generatora u testnoj vjetroelektrani.Theme of this thesis is modelling a part of power grid within which by the existing test wind power plant are connected two others. The whole model of the system was made with ETAP software. Changes of load flow were observed depending on the type of wind generators used at out test wind power plant (synchronous, asynchronous, double-fed induction generator), while the newly connected wind power plants were modeled with a double-fed induction generators. Also, depending on the failure of individual network elements, (n-1) contingency analysis was checked for all three types of wind generators in our test wind power plant
