Abstract

Conservativeness of the results and computation burden are the common drawbacks of the transient energy function method. The transient line potential energy method, on the contrary, is simple and fast since it has made no assumption on the system models and requires only a small number of locally measurable quantities. Besides transient stability assessment, the stability index it produced can be used to identify the critical cutset and vulnerable segments in the network. With the common use of global phase measurements, this method and its stability index shows a promising future in the on-line application on large power systems. Simulation studies on different systems, which include the IEEE 17-machine, UK 4-machine and 20-machine systems, validated that the proposed method and its stability index are effective and practical.
