LV automation solutions for resilient, flexible and optimized smart distribution grids

The world is undergoing an unprecedented revolution as result of the integration of renewable energies into the electrical system and the electrification of transport. To undertake this revolution, distribution system operators (DSO) must be prepared to integrate supervision and automation solutions that allow Low Voltage (LV) distribution networks to ensure a flexible and resilient grid. This paper will show various LV automation solutions (OLTC transformer, incoming switch-disconnector, phase and feeder switch disconnector ...) as well as specific use cases (overcurrent protection, thermal image protection, LV automatic recloser...) that can help to obtain multiple advantages for the LV distribution network. These advantages are: Improve quality of supply Optimise infrastructure investment needs and infrastructure use Defer or avoid asset reinforcement Carry out more efficiently planned maintenance, connection works and asset replacement Deal with unplanned interruptions by mitigating the effect of network outage
