Probabilistic Dispatch Assessment.
Half-hour security-constrained dispatch — across the full year, with the grid as a first-class constraint.
An SCED solver that minimises system cost under thermal, voltage and N-1 security limits. PTDF sensitivities trigger redispatch the moment a circuit binds — batteries, electrolysers and interconnectors all co-optimised in the same envelope.
The generation stack, resolved every half hour.
A representative week of security-constrained dispatch. When a monitored circuit binds, SCED chooses the cheapest redispatch over involuntary load-shed — every time.
Four stages, one optimisation envelope.
SCED solver
Linearised optimal generation mix at half-hour resolution — thermal, voltage and N-1 limits enforced.
PTDF redispatch
Auto-triggered on overload: the cheapest re-shuffle of injections, with no involuntary load-shed.
Sector coupling
BESS, hydrogen electrolysers and demand-side response co-dispatched in the same solve.
Interconnector co-opt
Cross-border flows optimised alongside domestic generation across all scenarios.
SCED chooses redispatch over load-shedding every time — and the slack variables emit precise signals on where new transmission, flex or interconnection pays back fastest.
