4 FAQs about [Expanding the capacity of grid-connected inverters]
Does grid impedance affect power transfer capability of grid-connected inverter?
Huang, L.; Wu, C.; Zhou, D.; Blaabjerg, F. Grid impedance impact on the maximum power transfer capability of grid-connected inverter. In Proceedings of the IEEE 12th Energy Conversion Congress and Exposition—Asia (ECCE-Asia), Singapore, 24–27 May 2021. (Accepted for publication). [Google Scholar]
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.
How to increase the maximum power transfer capability of a grid?
The maximum power curves in the inductive grid and resistive grid cases, with different SCRs and PCC voltages, are illustrated and benchmarked. It is revealed that increasing the SCR or reducing the R/X ratio of grid impedance can increase the maximum power transfer capability of the system.
How is maximum exploitation of the inverter's capacity achieved?
It is clearly evident that maximum exploitation of the inverter's capacity is achieved due to simultaneous injection of active and reactive power without curtailing the active power as shown in Fig. 8 d.
