Probabilistic Redispatch Assessment.

Find every thermal violation in all simulated hours — then price the cheapest way to clear them.

Stochastic security-constrained load flow against every N-1 contingency. Quad-boosters and HVDCs are optimally re-dispatched first; the residual is then costed zonally, nodally or hybrid.

Every overload, located in space and time.

A thermal-violation heatmap across circuits and months. The binding circuit lights up in the peak month — hover any cell for severity.

Inside the engine

From violation to priced residual.

01

Stochastic SCLF

DC load flow against the full monitored N-1 contingency set, across all hours.

02

Violation report

Per circuit, per hour — severity ratio with the binding contingency tagged.

03

Asset optimisation

A MILP re-dispatches QB angles and HVDC set-points to minimise overloads.

04

Residual cost

The remaining redispatch costed zonally, nodally or hybrid — the value of the next intervention.

The read

71% of overloads vanish once existing network assets are dispatched optimally — and the residual £412m/yr sets the floor on what new transmission, storage or demand response is actually worth.
