, Renewable and Sustainable Energy Reviews Valeria Boscaino, Dario Di Cara 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.
Can grid-connected PV inverters improve utility grid stability?
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.
What is a grid forming inverter?
In contrast, grid-forming units are predominantly used for voltage regulation instead of current regulation, reactive power can vary for voltage support, and grid-forming inverters natively provide uninterrupted power during islanded conditions.25
Does an inverter meet grid standards?
As aforementioned, the inverter is interconnected to the grid, so it should fulfill the grid standards as well. These standards includes power quality, grid ride through capability and islanding prevention . Power quality is mainly measured on the basis of Power Factor (PF) and Total Harmonic Distortion (THD).
What are the control objectives of grid-connected inverter?
The grid-connected inverter can distribute the active and reactive power according to the control. Therefore, the control objectives are designed as tracking active power and reactive power. The parameters of devices and circuits are shown in Table 13.1.
