On the Use of df/dt in Power System Emergency Control
Bevrani, Hassan, Ledwich, Gerard F., & Ford, Jason J. (2009) On the Use of df/dt in Power System Emergency Control. In 2009 IEEE Power Systems Conference & Exposition, 15 - 18 March, Seattle, Washington, USA.
This paper presents an overview of the key issues in the use of frequency rate change (df/dt) in power system emergency control schemes. The role of df/dt in designing effective under frequency load shedding (UFLS) plan is discussed. The impact of new variable renewable sources (such as wind and solar units) on system frequency gradient is analyzed, and the need for the revising of frequency performance standards, re-tuning of automatic UFLS relays, and use of ∆f/∆t rather than df/dt are emphasized.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
