In Smart Grids the flow of electricity and information is strictly interrelated with the management and control of the electricity supply system. ICT is not only an extension or a modernization of the power system equipment, but a fundamental requirement for supporting the distribution network monitoring, operation and control. To enable monitoring and control of the Smart Grid and accommodate the large realtime data flow between controlled equipment and the distribution management system it is necessary the deployment of advanced sensors and measurement systems along with the communication network infrastructure. In this paper two different strategies for power network monitoring and control are compared: an LTE-based centralized management approach and a 5G-based distributed management approach. The two types of communications systems are compared considering their performances during fault management in a Smart Grid scenario.
