AVC monitors the grid’s voltage levels and adjusts the reactive power output of generators in response to voltage deviations. When the voltage strays from its set standard, AVC sends signals to the generators to adjust their reactive power output, thereby bringing the voltage back within the acceptable range.
The primary difference between AGC and AVC lies in their control targets. AGC is focused on frequency control, while AVC is concerned with voltage control. Both parameters are crucial for the reliable operation of power systems, but frequency deviations generally have a more immediate and significant impact on the operation of electrical equipment.
Two of the most critical functionalities within an EMS are Automatic Generation Control (AGC) and Automatic Voltage Control (AVC). These features play a pivotal role in maintaining the stability of both frequency and voltage within the power grid. AGC is an automated control technology designed to maintain the frequency stability of a power system.
