Fast frequency response requirements for replacement of observed generator response during under frequency transients

, 2017
The aim of this investigation is to set requirements for optimal participation of battery energy storage systems in ancillary services. In this case the target is to maintain or improve the frequency nadir following loss of generation events. Phasor measurement unit data from approximately 50% of the generators on the island of Ireland is analysed for ...
