- Abstract
In this study we propose the optimization of the power quality in photovoltaic systems connected to grid. This system is composed of a grid powered by a photovoltaic generator (PVG) through two static converters controlled independently. A boost converter is a power electronic circuit that steps up a DC voltage to a higher level while regulating the output voltage of the PVG. this converter is control by incremental conductance (IC) which is one of the best maximum power point tracker technics (MPPT) to extract maximum power of the PVG, by dynamically modifying the operating voltage based on the instantaneous slope of the power-voltage curve. For a best quality of voltage and current injected to grid we use the simplified pulse width modulation (PWM) to command different structures of three-level inverters: A three-phase three-level flying capacitor (FC), a three-phase three-level neutral point clamped (NPC) and an active neutral point clamped (ANPC) three-phase three-level inverter. The proposed system was simulated in MATLAB Simulink to demonstrate its effectiveness in improving the power quality when injecting power from a photovoltaic generator (PVG) into the grid.
