To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
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.
4. Grid-connected inverter control techniques Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.
Controllers Reference Frames In grid-tied PV systems, inverter plays a prominent role in energy harvesting and integration of grid-friendly power systems. The reliability, performance, efficiency, and cost-effectiveness of inverters are of main concern in the system design and mainly depend on the applied control strategy.
