7Conclusion

All these facts clearly emphasize the necessity to build Smart Grids. In order to ensure effective management, it is necessary to create a sufficiently dimensioned data infrastructure between the source and the appliance, data centre and dispatching control. From this description, it can be concluded that building SG generates not only high costs, but also considerable demands on electromagnetic compatibility of cooperating and neighbouring systems.

Telecom operators and manufacturers of information and telecommunications devices, in the present situation of relative saturation of the classical telecommunications markets, have already understood that there is an essential need for the development of SG. It can become very promising for their current and future business.

It can be concluded that to ensure effective management, it is necessary to create a sufficiently dimensioned teleinformatic infrastructure between different energy sources and appliances, data centres, dispatching control and some other components of the energy companies. In this infrastructure, for technical and economic reasons, various PLC systems must be incorporated. An important aspect for the application of PLC/BPL resources is the possibility of combination with other teleinformatic technologies. PLC/BPL systems can provide not only the “last mile” section, but also access to the final distribution.
