Model validation is a basic and important work to ensure the dynamic simulation accuracy which influences the decision of power system design, planning, operation and control. Because large scale power systems have a great many components, the model validation work is very complex. A measurement-based model validation software(PSMV) is introduced in the paper. Current simulation accuracy can be evaluated...
Trajectory analysis method is an effective approach for evaluating the power system transient stability by proposed stability/instability indices based on the individual machine trajectory. The sensitivity of stability index with respect to some key parameters will be useful for control strategy making in power system operation. A trajectory sensitivity based algorithm for calculating the sensitivity...
Trajectory sensitivities provide a way to quantify the variation of trajectory resulting from (small) disturbances of parameters and/or initial condition. The trajectory sensitivity analysis has been applied in parameter identification, dynamic performance analysis of power system, and so on. The calculation of trajectory sensitivity is commonly based on the definition of itself. It relies on the...
