6 FAQs about [Analysis of the current status of photovoltaic inverters]

How to provide voltage support in PV inverter?

To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.

Can a PV inverter be used for condition monitoring?

Being the weakest component of the PV system, the inverter is mainly focused in this paper for condition monitoring. In a similar way, other components can also be monitored. The authors in [ 17] have discussed the PCA technique in detail. The data set including the current and voltage can be handled separately.

Why is inverter reliability important in a large-scale PV plant?

Abstract: In large-scale PV plants, inverters have consistently been the leading cause of corrective maintenance and downtime. Improving inverter reliability is critical to increasing solar photovoltaic (PV) affordability and overall plant reliability.

What is PV inverter efficiency?

For high-power applications, system efficiency is one of the most important factor to consider. The PV inverter efficiency is calculated as the ratio of the ac power delivered by the inverter to the dc power from the PV array. Many studies in the literature have been carried out to improve the efficiency of motor drive systems [19, 20].

Are CSI and VSI suitable for high-power photovoltaic (PV) applications?

In this study, a design of a medium-voltage current source inverter (CSI) and a conventional voltage source inverter (VSI) is presented for high-power (1 MW) photovoltaic (PV) applications.
