Control of Active and Reactive Power in Grid-Connected Photovoltaic Systems Using QBC and Dual Three-Phase Inverter

This research investigates the processes for controlling active and reactive power with dual inverter based grid-connected Photovoltaic (PV) systems. Integrating PV systems into the grid poses substantial issues for preserving power quality and stability, particularly in regulating active and reactive power flows. A Dual Three-phase Inverter(DTI) with QBC configurations offers a promising solution by distributing voltage stress and enhancing overall system efficiency and reliability using the D-Q Synchronous (DQS) approach. Advanced control algorithms for active and reactive power management and mathematical models customized for dual inverter systems are developed. Simulation results demonstrate the superior performance of dual inverters in maintaining grid synchronization and power delivery. The findings demonstrate the capabilities of dual inverter-based PV systems to improve the stability and efficiency of grid-connected renewable energy systems.
