For several decades, the traditional mindset for controlling large-scale power systems has been limited to local output feedback control, which means that controllers installed within the operating region of any utility company typically use measurements available only from inside that region for feedback, and, in fact, more commonly only from the vicinity of the controller location. Examples of such controllers include Automatic Voltage Regulators (AVR), Power System Stabilizers (PSS), Automatic Generation Control (AGC), FACTS control, HVDC, and so on.
