Power Grid OptimisationMaturity: concept

Load balancing, fault detection, grid stability and energy-distribution optimisation concept.

concept — An idea we find credible. Nothing has been built or measured.

What this is

The problem

A grid built for a few large generators is being asked to balance thousands of small, intermittent ones. Dispatch decisions that used to run hourly against a stable topology now need to run continuously against a changing one.

Where the current approach strains

Unit commitment and optimal power flow are hard combinatorial problems with hard physical constraints. Operators solve them with mature, heavily-tuned classical solvers. Those solvers are good — any alternative has to beat a strong incumbent, not a strawman.

What we are exploring

Whether the commitment sub-problem, which is the discrete part, can be formulated as QUBO and solved competitively. The continuous flow calculation stays classical.

What would have to be true

A formulation that respects the real constraint set rather than a simplified teaching version, and a head-to-head against the operator's existing solver on their own network data. Grid operations is not a domain that rewards optimism.

Provenance

Published as a case study on the legacy site. It described an application concept rather than a delivered engagement with measured outcomes, so it lives here with a maturity label instead.

Quantum-Accelerated Climate Forecasting

Climate models trade resolution against ensemble size, and decision-makers usually need what the budget cannot give: many detailed scenarios rather than one. We are looking at whether the sampling step alone can be restructured, leaving the physics to the classical models that already handle it well. No classical baseline has been run yet, which is why this sits as a concept.
