Security-constrained economic dispatch · GridSim DC-OPF
Optimal Dispatch
EuroRing is a neutral courier — the market decides who generates. This is the optimal reference it can be judged against: the cheapest generation that serves demand while keeping every cable within its thermal limit, solved as an exact security-constrained linear program over each nation's live marginal price. Where the network binds, the cheap dispatch cannot fully flow — that constraint is exactly what the market prices.

Binding constraints
These cables are held at their thermal limit — they are what stop the cheapest dispatch from flowing freely.

| L14 Iceland–United Kingdom | +2500 MW | 2500 MW | 100.0% |
