Abstract

The paper describes an algorithm for recursive identification of the power system composite load by using recursive least squares. The variation of the composite load components during slow voltage transients has been shown to deteriorate voltage stability margins. By combining the load identification and voltage stability monitoring, it is possible to make a better assessment of the risks associated with power system operation under heavy loading conditions
