D-Twin™ is a physics-grounded replica of your MV/LV network that solves a full power flow for every scenario. It turns open network and DER data into a defensible hosting-capacity and reinforcement decision, backed by numbers rather than rules of thumb.
Live Westnetz demo below ↓A live replica of your network that answers "what happens if" with physics.
Capabilities
A per-unit solver recomputes voltage, feeder loading and losses across every node and branch the instant a control moves. Nothing is illustrated. It's solved.
See how much more solar, wind or storage a feeder can absorb before the first voltage or thermal limit binds, the number every connection request should be judged against.
Step demand and DER to 2030 and 2040, add EV and heat-pump uptake, and watch where the network breaks first, and when.
Every operating point names the cheapest lever, reactive dispatch and tap control while headroom lasts, steel in the ground only when it's truly required.
In the field
The demonstrator reconstructs a medium-voltage network in the Eifel and populates it with distributed generation whose attributes follow the real OPSD schema, capacity, technology, grid-connection voltage, NUTS region and the Westnetz operator tag. On a sunny midday, unmanaged export pushes the network past its limits; step to 2040 and it degrades predictably.
