Research output: Contribution to conferencePaperpeer-review


Events as the Italy blackout 2003 and the grid splitting 2006 cause to bring up grid restoration and black-start ability as an urgent topic for both grid and power plant operators. In this paper the requirements for participation in grid restoration and lessons learned from black-start and island tests in Carinthia 2017 are discussed. The evaluation of the tests shows, that the nozzle provision results in an increased frequency stability due to the fast control reaction.
