Investigation Into The Local Nature Of Change Of Frequency In Electrical Power Systems, Damien Doheny

Student Journal of Energy Research

Over the coming years it is expected that considerably more wind power will be connected to the Irish power system. This will result in a power system that at times of high wind power penetration will operate with very low inertia, making the system susceptible to large rate of change of frequency (RoCoF) events due to disturbances. These high RoCoF events could result in the cascade tripping of generators connected to the grid resulting in complete shutdown of the system. This paper investigates the differences between local RoCoFs seen at individual buses and system wide RoCoFs seen across the entire …
