Integrating Load Frequency Control (LFC) with Supervisory Control and Data Acquisition (SCADA) systems represents a significant advancement in power system management, particularly in addressing the challenges of frequency stability in decentralized grids. Traditional LFC systems adjust generator outputs to counteract frequency deviations but often struggle with response time and accuracy, especially as renewable energy sources grow and demand fluctuates. This study examines the synergy between LFC and SCADA, emphasizing its application in meter control to enhance grid stability and efficiency. Simulation studies were conducted using a multi-area power system model in MATLAB/Simulink, comprising three interconnected control areas equipped with LFC modules. The integration of SCADA allowed for real-time data collection from Remote Terminal Units (RTUs) and rapid generation of control signals. A 200 MW load was introduced to test system responses under dynamic conditions. Results showed that SCADA-enabled LFC reduced frequency deviation by 40%, stabilizing at ±0.02 Hz within 5 seconds, compared to ±0.04 Hz in 12 seconds for conventional systems. Additionally, the response time improved to 3 seconds, halving the conventional system's 6-second response time, while Area Control Error (ACE) was minimized to zero in 8 seconds versus 15 seconds previously.
