A Novel Security Methodology for Smart Grids: A Case Study of Microcomputer-Based Encryption for PMU Devices

Coordination of a power system with the phasor measurement devices (PMUs) in real time on load and generation sides is carried out within context smart grid studies. Power systems equipped information pace external security threats. Developing which can resist against cyber threats considered indispensable for uninterrupted operation. In this study, two-way secure communication methodology underpinned by chaos-based encryption algorithm PMU proposed. The proposed uses IEEE-14 busbar optimum placement has been installed. hyperchaotic system-based method applied as new among devices. success results evaluated completeness data exchange, durations, complexity encryption-decryption processes, strength cryptography using microcomputer-based implementation. show that algorithms be directly embedded hardware units into PDC have very fast signal processing capabilities taking considerations acceptable delay protection measuring applications quality metering 2 ms 10 ms, respectively. While used TCP or UDP over IP-based IEEE C37.118, IEC 61850, 61850-90-5 frameworks, they also electronic cards, smartcards, tokens are utilized authentication components.
