FAQ
Q AMI vs traditional meters?
A
AMI with two-way communication, minute-level data, remote reading, time-of-use rates, load monitoring and outage detection. Traditional meters require on-site reading. Europe reached 80%+ penetration by 2020.
Q VPP virtual power plant?
A
Aggregates distributed resources (rooftop PV, home storage, V2G EVs, controllable loads) to participate in electricity markets as a unit. Next Kraftwerke (DE), Tesla VPP and Sonnen lead Europe.
Q Distribution automation pain points?
A
MV blind zones without monitoring; reverse power flow at PV > 30% penetration causes voltage violations; protection coordination needs directional relays for bidirectional flow. Solved via IEC 61850-9-2 LE + smart terminals.
