What is a grid-connected inverter?In the grid-connected inverter, the associated well-known variations can be classified in the unknown changing loads, distribution network uncertainties, and variations on the demanded reactive and active powers of the connected grid.
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.
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.
Should auxiliary functions be included in grid-connected PV inverters?Auxiliary functions should be included in Grid-connected PV inverters to help maintain balance if there is a mismatch between power generation and load demand.
What is grid side control?The grid side control performs several operations such as the control of the reactive (Q) and the active power transferred to the grid, the frequency and the voltage regulation, the grid synchronization, the control of the DC link and a high quality of the injected power . 4.1.
