The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined. The various control techniques of multi-functional grid-connected solar PV inverters are reviewed comprehensively.
In Ref. , the authors propose a low voltage ride through (LVRT) control strategy for a single phase grid connected PV system. The LVRT strategy allows keeping the connection between the PV system and the grid when voltage drops occur, ensuring the power stability by injecting reactive power into the grid.
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.
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.
Around 75% of the PV systems installed in the world are grid connected . In the grid-connected PV system, DC-AC converters (inverters) need to realize the grid interconnection, inverting the dc current that comes from the PV array into a sinusoidal waveform synchronized with the utility grid [2, 3].
Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid. The application of the system will determine the system’s configuration and size. Residential grid-connected PV systems are typically rated at less than 20 kW.
