Testing, troubleshooting and modelling tools for communication part of Smart Grid

This paper deals with a data transfer testing and modeling in communication networks supporting energy distribution. The concept of Smart Grid, which promises highly efficient and dynamic energy systems, has to be backed by convenient communication systems. The contemporary electrical grid incorporate some form of the digital communication to be able to deliver desired availability and reliability at all levels. This means that the communication systems are inseparable from the electrical grid itself. While power-engineering uses well proven methods for the grid testing, the data networking, in this particular area, is still evolving. The paper analyses advanced methods for testing and modeling of data transfers in communication networks and presents selected practical experience.
