Abstract

The Security of Power networks is one of the main focuses of operation utilities and measuring parameters of lines, buses, and other substantial equipment has particular importance for them. Essential role of measuring and control in normal operation of smart grids makes cyber security an important necessity for todays and future power grids. Therefore, as the power network depends on communication systems and information technologies, using phasor measurement units (PMUs) in order to measuring, protection and control become expanded. Reconfiguration of the power network is implemented for several reasons including loss reduction, improving voltage profile, power quality, etc. In this paper power network observability through PMUs which are allocated optimally is analyzed in reconfigured networks in order to investigate the network cyber security. Performance of the proposed method is evaluated in 14-bus and 30-bus IEEE.
