Impact of interference on digital information flow in dynamically changing PLC network topology cyber security in smart grid

Abstract

In recent years, electric power systems, in order to improve their efficiency, are increasingly using the latest innovations in the field of information and communication technologies (ICT). The combination of those systems, year by year, used of more and more sophisticated communication algorithms leading to automatic management of energy distribution process. The use of ICT communication equipment in electric power systems is certainly a big advantage, but it also entails some safety issues. The development of technology, falling costs of production, as well as the development of more and more computer applications contributed significantly to the rapid development of computerization in all aspects of our lives. Considerable progress ICT services allows their effective use in intelligent power networks (Smart Grids). Particularly important in the efficient management of low voltage networks (Smart Metering) to know the network topology dynamically by emerging transmission of digital information to the physical network operator.
