Steadily increasing demand for electricity has led to today's electric power
networks often being stressed to their stability limits. Improved methods of stability
monitoring and control placement are needed to manage the increased stress on
power networks. Modal participation factors have been used for several decades
in the analysis of modal behavior in power networks. Recently a dichotomy was
discovered in modal participation, indicating that the participation of system states
in system modes should be calculated differently from the participation of system
modes in system states. This masters thesis numerically explores possible roles for
these new participation factor definitions in power network monitoring and control.
The results suggest that the mode in state participation factors are best employed in
modal monitoring (especially in deciding which variables to monitor to best detect
specific modes), while the state in mode participation factors are best suited to
control applications (such as controller placement).
