Title: Measurement-based voltage stability assessment for load areas addressing <italic>n</italic>−1 contingencies
Authors: Fengkai Hu;Kai Sun;Di Shi;Zhiwei Wang
Year: 2017
Publisher: IET
Abstract: This study proposes an online measurement-based method for <i>n</i>-1 voltage stability assessment on a load area by means of an equivalent system of <i>N</i> + 1 buses introduced by Hu <i>et al</i>. to represent <i>N</i> boundary buses of the load area and the external system. This method utilises real-time synchro-phasor measurements on <i>N</i> boundary buses and online state estimation on the load area to analyse <i>n</i>-1 sensitivities for equivalent transfer admittances and power flows by means of a modified line outage distribution factor in order to estimate the voltage stability margin of power transfer to each boundary bus under an anticipated <i>n</i>-1 condition. The method is demonstrated on the Northeast Power Coordinating Council 48-machine, 140-bus power system.
