ABSTRACT
The Smart Grid is a modern power system that uses information and communication technologies to provide more efficient, reliable, and sustainable energy than a traditional power grid. Different from the conventional power grid, a smart grid allows for a bidirectional flow of information and energy, and the penetration of renewable energy sources, smart parking lots and prosumers makes the smart grid more flexible but also challenging to control. Concerns about the dependability and security of the communications infrastructure are affecting the adoption of synchrophasor technology, making it all the more essential to secure the network connections between Phasor Measurement Units (PMUs) and Phasor Data Concentrator (PDCs) to ensure the reliability of smart grid operations. In the power system, security gateways are used in critical connections, such as, communications between PMUs and PDCs, to encrypt and decrypt packets.
