Optimal LFC SMC for three-area power system with high penetration of PV

الملخص EN

Electrical power systems are subjected to new trends appearing in grid structuring, electrical power sources, new control strategies, etc.

The introduction of inverterbased distributed energy resources to replace conventional synchronous machines depletes the mechanical inertia, and causing the system to become more sensitive to disturbances.

This paper proposed a simple and reliable solution to assure sufficient frequency stability of electrical power systems when subjected to high penetration of decoupled distributed generation.

To achieve this, a decentralized sliding mode control was designed to operate as a compensator for conventional load frequency controllers.

Subsequently, PV farms and battery energy storage systems were interconnected.

Simulated network under different configurations were conducted using MATLAB.
