Improved Load Frequency Control Of Two-Area Power System

The power lines are connected in an interconnected power system through tie lines and Load Frequency Control (LFC) places the frequency and tie line power errors zero to keep the system in steady state condition. This paper represents an effective decentralized Load Frequency Control (LFC) by means of the concept of Active Disturbance Rejection Control (ADRC). The performance of ADRC based LFC is compared with PID based LFC in two area power system. Simulation is done by MATLAB Simulink and the results demonstrated the better robustness and dynamic performances with ADRC based LFC over PID based LFC.
