The PV inverter systems are widely operated in stand-alone and grid-connected modes of operation. The stand-alone systems are beneficial in remote areas that are isolated from the power distribution network. However, for integration with a micro grid, the PV inverter system would need to operate in grid-connected mode.
The three-phase grid-connected inverters run in the current control mode in synchronization with the grid. As shown in Fig. 7, a reference-frame transformation-based control approach is used to achieve grid-connected inverter control.
