Automatic generation control for multi-area power system

What is automatic generation control (AGC)?

1. Introduction Automatic Generation Control (AGC) plays an important role in the large scale multi-area interconnected power systems to maintain system frequency and tie-line powers at their nominal values.

Which controllers are used for automatic generation control?

To make the interconnected power system more reliable, economic, and effective, secondary controllers such as PID, PI-PD, and ADRC are used for automatic generation control.

Why is automatic generation control important?

It is well known that automatic generation control plays a vital role in the power system to maintain the frequency and tie-line powers to the reference value by using secondary controllers. Hence, the selection of proper secondary controller is crucial.

What controllers are used in three area power system AGC?

Block diagram of IEEE three area power system Simulation of three area power system AGC using ADRC Simulation of three area power system AGC using PID/PI-PD controllers For the three area power system, ADRC, and PID and PI-PD controllers are employed as secondary controllers. Choosing a good secondary controller is very important.

Why is AGC important for interconnected power system?

AGC is useful for the operation of interconnected power system. The important aspect of the system’s operation and control is to supply quality power. AGC always tries to maintain the frequency and tie-line powers to scheduled values by controlling the generation automatically to meet the load demand.

How is automatic generation control simulated?

Automatic generation control is simulated with different secondary controllers like PID tuned by the PSO algorithm, ADRC controllers by Nagarjuna [3, 9, 10, 11], and fuzzy controller by Yousef . Automatic voltage regulator (AVR) with ADRC by Nagarjuna , PSO-PID controller by Zwe-Lee Gaing simulated.
