The daily varying of power output by a generator.
Regulation of the power output of electric generators within a prescribed area in response to changes in system frequency, tieline loading, or the relation of these to each other, so as to maintain the scheduled system frequency and/or established interchange with other areas within predetermined limits.
An electric system's process of regulating its generation to follow the changes in its customers' demand. This capability is especially important for firm power and delivery of all-requirements service.
Method of operating a fuel cell system to generate a varying amount of power depending on the load demanded. search
An electric system's or plant's ability to regulate its generation to follow the instantaneous changes in its customers' demand.
continuous balancing of generation and load accomplished by committing online generation whose output is raised or lowered as necessary to follow moment-by-moment changes in load.
Practice of matching the generation destined to serve a load, to that load, on a real-time basis.
1. The obligation of the wheeling utility to provide from its own generating sources any difference between the amount of power being wheeled and the instantaneous requirement of the customer receiving, or the supplier delivering the wheeled power. 2. Load following falls into two categories: (a) dedicating sufficient generating capacity to the automatic generator control (AGC) mode to allow them to follow load, and (b) monitoring mismatches between intended and actual interchanges between control areas, and transmitting control signals to AGC generators to minimize this mismatch. Both require a system to record mismatches (over-runs and under-runs). Load following is important because it helps maintain system frequency. Otherwise, if demand exceeded supply, generators would slow down; and if supply exceeded demand, generators would speed up. Both situations could result in an unstable situation which could lead to a widespread outage.
An ancillary service that adjusts generation to meet the hour-to-hour variations between generators and demands.
