Time domain simulation based on-line dynamic stability constraint assessment

Large interconnected power systems around the world are often constrained by stability limits rather than thermal or voltage limits. This is known to cause significant additional costs on the system operation as guidelines and limits produced by off-line studies are conservative and hence economically inefficient. The additional operation costs can be minimised if the stability constraints could be assessed accurately on-line using real-time system information. This paper presents the development of a time domain simulation based assessment tool which could be used for on-line dynamic stability constraint assessment of large complex power systems.
