The Role of SCADA System in Facilitating Automatic Generation Control (AGC) for Interconnected Power Systems A Case Study of Data Acquisition and Command Execution in Indian Utility Regions

  • Abstract:
  • Reliable and stable operation of interconnected power systems requires real-time monitoring, coordination, and control of generating units across multiple regions. Automatic Generation Control (AGC) ensures that system frequency and scheduled tie-line power exchanges are maintained within acceptable limits. Supervisory Control and Data Acquisition (SCADA) systems play an integral role in enabling AGC by providing real-time telemetry, executing control commands, and facilitating two-way communication between generating plants and Load Dispatch Centres (LDCs). This paper presents a detailed study of the role of SCADA in facilitating AGC operations with a case study focusing on data acquisition and command execution within an Indian utility region, specifically referencing NTPC Dadri and POSOCO’s pilot AGC implementation. The study highlights data flow architecture, communication protocols, telemetry performance, and system response under varying load conditions. Experimental results indicate that enhanced SCADA–AGC coordination significantly improves system frequency control and reduces area control error (ACE) deviations.
