The irrelevance of electric power system dynamics for the loading margin to voltage collapse and its sensitivities
نویسنده
چکیده
The loading margin to a saddle-node or fold bifurcation measures the proximity to voltage collapse blackouts of electric power transmission systems. Sensitivities of the loading margin can be used to select controls to avoid voltage collapse. We analytically justify the use of static models to compute loading margins and their sensitivities and explain how the results apply to underlying dynamic models. The relation between fold bifurcations of the static models and saddle-node bifurcations of the underlying dynamic models is clarified.

The Irrelevance of Load Dynamics for the Loading Margin to Voltage Collapse and Its Sensitivities
The loading margin to a saddle-node orfold bifurcation is a useful and basic index of proximityto voltage collapse. Sensitivities of the loading margincan be used to select controls to avoid voltage collapse.This paper justifies the use of static power models to com-pute loading margins and their sensitivities. In particular,dynamic load models may be reduced to static e...

متن کاملOptimal Load Shedding for Voltage Stability Enhancement by Genetic Algorithm
Outage of a heavily loaded transmission line or tripping of large generating unit may lead the system toward collapse. Under such circumstances, compared to other measures, load shedding procedure is an efficient method to make the power system voltage stable when many system variables are out of their normal ranges and the system is driven toward collapse. This paper introduces the concept of ...
متن کاملContingency Ranking for Voltage Collapse via Sensitivities from a Single Nose Curve
The change in the loading margin to voltage collapse when line outages occur is estimated. First a nose curve is computed by continuation to obtain a nominal loading margin. Then linear and quadratic sensitivities of the loading margin to each contingency are computed and used to estimate the resulting change in the loading margin. The method is tested on a critical area of a 1390 bus system an...
