This article presents commonly used multilevel inverter technologies for grid-connected PV applications, including five-level inverters, single-phase nonisolated inverters, and three-phase, isolated cascaded H-bridge inverters. Detailed discussions are presented, along with characteristics of PV applications.
When modeling grid-connected inverters for PV systems, the dynamic behavior of the systems is considered. To best understand the interaction of power in the system, the space state model (SSM) is used to represent these states. This model is mathematically represented in an expression that states the first order of the differential equation.
However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.
In a grid-connected PV system, the inverter plays a critical role in ensuring high energy conversion efficiency while meeting stringent grid standards for power quality and safety 7.
