6 FAQs about [Reactive capacity of photovoltaic inverter]
Do inverters provide reactive power at full power?
Inverters used for solar PV and wind plants can provide reactive capability at partial output, but any inverter-based reactive capability at full power implies that the converter need to be sized larger to handle full active and reactive current.
How much power can a PV inverter produce?
Like inverter-based wind generators, PV inverters are typically designed to operate within 90% to 110% of rated terminal voltage. Reactive power capability from the inverter, to the extent that is available, varies as a function of terminal voltage.
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.
Do solar PV inverters need Dynamic Reactive support?
Sometimes, external dynamic reactive support is required to assist with voltage ride-through compliance. During periods of low wind or solar resource, some generators in the plant may be disconnected from the grid. The DC voltage for solar PV inverters may limit the reactive power capability of the inverters.
How is inverter capacity exploited?
In this case, the inverter capacity is exploited by partially injecting both active and reactive power under fault conditions. Since the generated active power is not high, the remaining inverter capacity is utilized by injecting reactive power as in (30).
Does DC input voltage affect reactive power capability?
Reactive power capability from the inverter, to the extent that is available, varies as a function of terminal voltage. Furthermore, DC input voltage could also affect reactive power capability where single-stage inverter designs are used. For example, a low maximum power point (MPP) voltage could reduce the lagging reactive power capability.
