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.
Anti-islanding is a critical safety feature in grid-connected solar PV systems that prevents the system from continuing to supply power to a local grid section when the main utility grid fails or is disconnected. An "island" refers to an isolated portion of the grid that remains energized by the solar system, posing serious risks:
Grid-tied solar systems must integrate seamlessly with the utility''s overall protection scheme. The anti-islanding device''s overcurrent and reverse power protection functions work in conjunction with grid-side circuit breakers and fuses, forming a multi-level protection system.
