Interconnection of power systems with different under-frequency load shedding schemes

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...

Zusammenfassung:	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.
