Abstract

This letter presents a novel method to determine the weight coefficient existing in the model of network reconfiguration during power system restoration. The data envelopment analysis (DEA) method incorporating preference information is employed to implement the modeling and evaluation of the weight coefficient with respect to each transmission line. Some practical factors involving line charging reactive power, weather condition, equipment reliability, line operation time, and transmission capability are taken into account during analysis.
