Abstract

Probabilistic assessment of power system transient voltage stability is a useful complement to determinate evaluation. The linear boundary of dynamic security region of the controlling unstable equilibrium point was determined on the basis of dynamical system theory. Consequently, power system transient voltage stability probabilistic model was established. The model can effectively consider many uncertain factors, such as generator output and internal potential, load active power and reactive power, fault location, fault type, fault-clearing time, etal. The simulation of New England 39 bus test system shows that the proposed assessment strategy is effective and accurate.
