Influence of power plants on renewable sources on transmission network stability and fault ride-through

U ovome radu dan je teorijski pregled utecaja elektrana na obnovljive izvore energije na stabilonst napona, frekvencije i kuta elektroenergetskog sustava, te prolazak kroz kvar. U programskom alatu DIgSILENT PowerFactory izvršena je simulacija dodavanja jedne vjetroelektrane u sustav kako bi se analizirao njen utjecaj na stabilnost napona i kutnu stabilnost, te su prezentirani rezultati analize.In this paper a theoretical overview of the impact of renewable energy sources on voltage stability, frequency stability and angular stability is described, as well as fault ride through. A simulation was carried out using software package DIgSILENT PowerFactory for the case of adding one wind power plant to an existing system so that it's impact on voltage and angular stability could be analyzed. The reusults of the analysis are presented
