Diagram of grid-connected photovoltaic system . The inverter, used to convert photovoltaic dc energy to ac energy, is the key to the successful operation of the system, but it is also the most complex hardware.
In general, on the basis of transformer, the grid-connected PV inverter topologies are categorized into two groups, i.e., those with transformer and the ones which are transformerless. Line-frequency transformers are used in the inverters for galvanic isolation of between the PV panel and the utility grid.
Single stage topologies have been studied, with a special focus on multilevel converters, which are effective for improving power quality. As it has already been stated, the proper operation of a grid-connected PV system is ensured by the fast and accurate design of its control system.
This paper aims to provide a broad overview of the various grid-connected PV system configurations and their power converter technologies for applications in single- and three-phase utility power systems. Grid-connected PV systems presented include module-integrated, string, and centralized configurations.
