Low Computational Burden Predictive Direct Power Control of Quasi Z-Source Inverter for Grid-Tied PV Applications

This paper proposes a simplified predictive direct power control for the grid-tied quasi Z-source inverter. The proposed implements model structure to achieve maximum obtainable from collected PV source. delivered grid is managed compensate reactive and, as needed, ensure grid’s stability. A inverter developed in which can operate with fixed switching frequency without weighting factor. space vector modulation uses three appropriate vectors that are selected and applied using precalculated times during each period, required determined only one sector diagram, taking all of information other sectors, leads reducing computational burden. Simulation results comparative study used confirm performance capable tracking generating fast-tracking dynamics, ensuring ac voltage desired, better active reference lowest ripple. current harmonics were tested conformed IEEE-519 standard. Additionally, PDPC experimentally validated Hardware-in-the-Loop emulator C2000TM-microcontroller-LaunchPadXL TMS320F28379D kit, establishing usability good result our approach terms requirements.
