Automatic Generation Control Strategies in Conventional and Modern Power Systems: A Comprehensive Overview

Automatic generation control (AGC) is primarily responsible for ensuring the smooth and efficient operation of an electric power system. The main goal AGC to keep operating frequency under prescribed limits maintain interchange at intended level. Therefore, system must be supplemented with modern intelligent techniques provide adequate supply. This paper provides a comprehensive overview various models in diverse configurations Initially, history explored basic multi-area interconnected presented. An in-depth analysis methods used mitigate issues provided. Application fast-acting energy storage devices, high voltage direct current (HVDC) interconnections, flexible AC transmission systems (FACTS) devices are investigated. Furthermore, employed different renewable overviewed summarized tabulated form. microgrid smart grid also presented detail. A thorough deregulated provided by considering contract scenarios. Moreover, additional objective economic dispatch investigated worldwide practices Finally, concludes emphasis on prospective study field AGC.
