Abstract :
Development of power systems leads to new interconnections that can join power systems with different approaches regarding under-frequency load shedding (UFLS). Parallel operation of different UFLS schemes is analyzed in this paper considering possible UCTE/NORDEL and IPS/UPS interconnection. It is shown that due to differences between UFLS schemes the interconnection´s stability can be endangered.
