Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.
The different solar PV configurations, international/ national standards and grid codes for grid connected solar PV systems have been highlighted. The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined.
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.
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
The inverter is connected to the grid by an LCL filter. The simulation system block diagram is shown in Figure 9. Simulated system block diagram. The simulation carries the three PV modules which are connected in series.
For security reasons, the PV grid-connected inverters must be disconnected from the grid when the utility is disabled or out of operation. Once the grid is out, the PV system is operating in islanding mode, and this mode must be detected to shut off the system and separate it from the utility.
