Abstract

The increasing adoption of distributed generation (DG) systems, driven by their numerous advantages, has led to a growing utilization of hybrid systems. Multilevel converters have emerged as essential components in power electronics applications, offering benefits such as harmonic reduction. However, designing effective control strategies for multilevel inverters presents challenges. This paper proposes a multi-DG quasi-Z-Source Inverter (qZSI) designed with a cascaded H-bridge controller. The incorporation of qZSI in the system enhances reliability and component safety while enabling the implementation of additional shoot-through control. This feature facilitates the balancing of inequalities arising from the two DG sources, thereby improving disturbance rejection. Furthermore, a current control scheme is implemented on the AC side to seamlessly feed active power into the grid without introducing distortions in current injection. Overall, the proposed system addresses key challenges in multilevel inverter design and offers a promising solution for efficient and reliable grid integration of DG systems. This work is thus useful in variety of applications, including electric vehicles and environment sustainability. [ABSTRACT FROM AUTHOR]
