The aim of this thesis is to explore the limits of communication methods in smart grid networks by analyzing its performance-simulations. First I give a short overview of smart grid technologies focusing on the methods of communications from the physical layer up to the management. The next step is to choose existing, or soon to be realized communicating smart grids for the simulations. There are many possible candidates - but to make the decision easier a secondary goal was set; to find a smart grid solution which could be adapted to our local environment in Hungary. So finally a modern, reliable and therefore very expensive method, the Fibre-Wireless realization, and its Russian counterpart - which is based on a different set of networks and elements fitting to the environmental and economical limits - were chosen. These two smart grids are also representing most of the communication methods mentioned in the first chapters. The incrementally built simulations are conducted in the OMNeT++ environment - several scenarios are modelled, including broken links, cross connections - each using thousands of communicating nodes and parametrized channels.

After evaluating the simulations, both the performace limits of the network, and the optimal parameters of communication (eg. datarates, packet sizes, data sending frequency) can be determined. To accomplish these tasks, a good overview of the smart grids and generally computer networks are required, therefore studying papers and other thesises are necessary. As the result of this thesis I will have an idea of smart grids, and also exact parameters for communication optimalization regarding the two chosen smart grid realizations.
