Description
Summary:This paper proposes a state-of-art advanced adaptive control law for grid-interfaced Renewable Energy Sources (RES) that enhances the power quality as well as the power factor at the Point of Common Coupling (PCC) under various system's conditions, including load and transmission lines variations. The presented law is a Lyapunov-based Adaptive Sliding Mode Control where the parameters of the system are neither known nor exactly estimated, but rather their estimates would guarantee a global asymptotic stable controller steady-state error. The proposed controller was simulated under varying system's parameters through introducing a new load during the simulation time. The simulation results verified the analysis, and the controller adaptability as well as its dynamic response were both satisfactory and could outperform the conventional sliding mode controller by achieving lower steady-state error that ultimately resulted in lower current Total Harmonics Distortion.
