Monitoring and control of LV networks - WG 2019-5

LV networks have emerged as networks of significant importance in the architecture adopted for the implementation of the concept of smart grids for the following reasons: 

• network automation and control functions expand and increasingly cover LV networks;
• in some advanced metering infrastructures architecture options, LV networks become a key level of management of the system;
• LV systems emerge as active agents in the management of voltage and the balancing of generation and demand;
• LV networks management will play a major role in the implementation of energy communities and microgrids.

LV network automation is made possible by the implementation of many new features: circuit­breakers with electronic protection unit, measurements and communication, signalling from circuit-breakers/protection in case of fault, motorized circuit-breakers or switches, remote control of circuit-breakers, advanced protections, utilization of fault data for fault location, utilization of smart meter data and infrastructure, ... 

The working group will investigate: 

• real-time remote availability of the information on the status of the network (including fault location);
• real-time remote availability of the values of the electrical parameters (current and/or voltage);
• smart switches, breakers and sensors for LV network; 
• new MV/LV interface solutions; 
• automatic and remote network reconfiguration capability;
• flexibility of distributed resources from LV clients .
