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-connected inverter?
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.
Why is a DC component injected to the inverter output through the ground path?
A DC component may be injected to the inverter output through the ground path, also due to non-ideal switching characteristics of semiconductor devices, asymmetric switching behaviour and gate drive circuits or offset drifts and nonlinearities in the control system.
What is inverter control methodology?
The inverter control methodology is based in two cascade loops: a fast internal current loop and a slow external voltage loop. The current loop controls the grid current and it effects the current protection and the power quality levels.
