IntroductionĪ smart grid is defined as the provision of conventional electric power grids with modern information technologies. While proposed algorithms can be used in TCP or UDP over IP-based IEEE C37.118, IEC 61850, and IEC 6 communication frameworks, they can also be embedded into electronic cards, smartcards, or smart tokens which are utilized for authentication among smart grid components. The results show that the proposed microcomputer-based encryption algorithms can be directly embedded as encryption hardware units into PMU and PDC devices which have very fast signal processing capabilities taking into considerations the acceptable delay time for power system protection and measuring applications and quality metering applications which is 2 ms and 10 ms, respectively.

The success of results is evaluated by the completeness of data exchange, durations, the complexity of encryption-decryption processes, and strength of cryptography using a microcomputer-based implementation. The proposed hyperchaotic system-based encryption method is applied as a new security methodology among PMU devices.

The proposed system uses the IEEE-14 busbar system on which the optimum PMU placement has been installed. In this study, a two-way secure communication methodology underpinned by a chaos-based encryption algorithm for PMU devices is proposed.

Developing a smart grid which can resist against cyber threats is considered indispensable for the uninterrupted operation. Power systems equipped with information systems in a smart grid pace with external security threats. Coordination of a power system with the phasor measurement devices (PMUs) in real time on the load and generation sides is carried out within the context of smart grid studies.
