| Notes | Though multi-step high order Taylor method is an effective tool for power system transient stability analysis, it needs further improvement by dynamic order control and parallel calculation strategy. Based on the numeric stable domain theory, this paper proposes a novel multi-step dynamic-order Taylor method. With the characteristics of transient stability analysis, the paper adopts different derivative order for Taylor expansion according to the simulation accuracy. Furthermore, based on parallel calculation technology, a high order Taylor parallel transient stability analysis strategy is proposed. Finally, the result of New England 10-machine 39-bus system shows the proposed parallel dynamic-order Taylor is a good transient stability analysis tool with a stable numerical region and could eliminate the calculating redundancy of fixed-order Taylor method; and it efficiently improves the transient stability analysis efficiency when combined with parallel calculation technology.
