Decentralized Sliding Mode Load Frequency Control for Multi-Area Power Systems

This MATLAB/Simulink model implements a Decentralized Sliding Mode Controller (SMC) for Load Frequency Control (LFC) in multi-area interconnected power systems. The product is designed to maintain system frequency and tie-line power exchanges within permissible limits under varying load conditions and disturbances.

The decentralized control strategy enables each control area to operate independently without requiring full system information, making the approach scalable and robust for large-scale interconnected grids. Sliding mode control ensures strong robustness against model uncertainties, parameter variations, and external disturbances, outperforming conventional PID-based LFC schemes.

Key Features:

• Multi-area interconnected power system modeling in MATLAB/Simulink.

• Implementation of decentralized SMC-based LFC for each control area.

• Robust performance under load disturbances and parameter variations.

• Enhanced frequency stability and tie-line power regulation.
