Power system operations is a term used in electricity generation to describe the process of decision-making on the timescale from one day (day-ahead operation[1]) to minutes[2] prior to the power delivery. The corresponding engineering branch is called Power System Operations and Control.
Day-ahead operation
Day-ahead operation schedules the generation units that can be called upon to provide the electricity on the next day (unit commitment). The dispatchable generation units can produce electricity on demand and thus can be scheduled with accuracy. The production of the weather-dependent variable renewable energy for the next day is not certain, its sources are thus non-dispatchable. This variability, coupled with uncertain future power demand and the need to accommodate possible generation and transmission failures requires scheduling of operating reserves that are not expected to produce electricity, but can be dispatched on a very short notice.[1]
