Grid-Connected PV Using Sliding Mode Based on Incremental Conductance MPPT and VSC

Our study puts forward a new method to track the maximum power point (MPPT) of the photovoltaic (PV) connected a grid: A sliding mode controller based on incremental conductance (INC) is designed to be implemented to a DC/DC boost converter well-arranged to improve its performances and to achieve a maximum power point of PV. The Incremental Conductance-Sliding Mode Control (INC-SMC) offers an accurate and good convergence to the maximum power point (MPP) when the INC provides the reference voltage and the sliding mode control (SMC) realizes the stability of the system. Next, the voltage source control (VSC) was utilized DC/AC inverter to operate as a charge controller for the grid parameters.
