摘要

In this paper a novel method called Vector Analysis (VA), using a new instability detection index is proposed to provide wide area voltage stability for the power systems. The index extraction process relies on measurements of active and reactive powers from connected buses to the generator bus. Moreover, as long as VA predicts voltage collapse, through disconnecting weak lines and based on network graph, zoning is carried out in the power system. For the aim of system observability, phasor measurement units (PMUs) placement, have also been optimized by Swarm Robotics Search & Rescue (SRSR) algorithm. Simulations have been carried out on IEEE 39- bus test system which demonstrates the accuracy of index distinction in voltage stability assessment and system zoning.
