Technical FAQs 4

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

What is a low voltage ride-through (LVRT) inverter?

Low voltage ride-through (LVRT) capable inverters inject reactive power to help with fault recovery during periods of grid sags in addition to withstanding grid sags 13, 14. The goal of the LVRT inverter is to maintain grid connectivity during transient faults by disabling and de-activating the under/over voltage and over current relays.

Can multimode inverter control improve LVRT capability?

The proposed control strategy utilizes the multimode operation of the inverter to enhance the system's LVRT capability. The research paper provides a detailed analysis of the experimental results, including the performance of the system under different operating conditions and voltage disturbances.

How important is LVRT capability in grid-connected solar PV systems?

The paper highlights the importance of LVRT capability in grid-connected solar PV systems, as it ensures the stability and reliability of the grid during voltage fluctuations. The proposed control strategy utilizes the multimode operation of the inverter to enhance the system's LVRT capability.
