Simulation Of Smart Grid Security And Vulnerability Analysis Using Pmu State Estimation

摘要

The electricity demands are increased rapidly with low power losses and low energy costs. To minimize the power loss and achieve load demand with that developing new energy sources based on Renewable energy sources are necessary to think. The controlling and achievement of about goals is difficult in the normal power grid, so smart grid development is increased in the recent few years. While the biggest issues related to SG is security. The vulnerability of SG against cyber-attacks is discussed in this paper. The Bad data injection, False Data injection, and cyber-attacks are the most focusing challenges reviewed in this paper. The PMU state estimation is one promising solution for SG security. So we have shown the SG security analysis for the IEEE 14-bus system using Matlab-Simulink. The simulation results show that PMU provides protection against cyber-physical attacks as well as reliable and secure operation of S.G.
