AGC systems enable a grid operator to centrally and automatically manage the output of interconnected generators, storage devices, and controllable loads to maintain reliable and safe system operations.
What is automatic generation control (AGC)?
This review presents a state-of-the-art literature review of Automatic Generation Control (AGC) control strategies for power systems containing renewable energy sources. The incorporation of renewable energy into the power system has a large impact on the stability, reliability, economy and security of the power system.
Why is automatic generation control important?
The concept of automatic generation control has an immense role in providing quality power in an interconnected system. To obtain quality power by controlling the oscillations of frequency and tie-line power, a proper controller design is necessary.
The aim of this paper is to study the automatic generation control (AGC) in a restructured power system. The power system under study has five different diversified energy sources assisting some real time nonlinearities like generation rate constraint (GRC), governor dead band (GDB), and boiler dynamics.
Because of the uncertainty of the external environment, high penetration of renewable energy such as wind power and solar energy in the modern power system renders the traditional automatic generation control (AGC) methods more challenging.
Is a single load change necessary for automatic generation control (AGC)?
Modern power systems must be resilient to sudden load variations in order to keep the system stable. For Automatic Generation Control (AGC), single load change is impractical and need further analysis.
Does automatic generation control work in a two-area interconnected power system?
For Automatic Generation Control (AGC), single load change is impractical and need further analysis. This study comprehensively explore the performance of AGC in a two-area interconnected power system, focusing on a wide range load variations that can exists in realistic power systems consisting from 100 to 300 MW in both increments and decrements.
