6 FAQs about [How to generate reactive power with photovoltaic inverter]

Can a PV inverter be used as a reactive power generator?

Using the inverter as a reactive power generator by operating it as a volt-ampere reactive (VAR) compensator is a potential way of solving the above issue of voltage sag . The rapid increase in using PV inverters can be used to regulate the grid voltage and it will reduce the extra cost of installing capacitor banks.

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.

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 do photovoltaic inverters work?

Many photovoltaic inverters, connected to common bus, consist a structural part of a solar photovoltaic station. As we said earlier, each of them can either absorb reactive power component, preventing voltage boosts in connection point, or generate it, preventing voltage falls.

Can a solar PV inverter be disconnected from the grid?

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. This should be taken into consideration when specifying reactive power capability for variable generation plants.

How do wind generators & solar PV inverters work?

Individual wind generators and solar PV inverters typically follow a power factor, or reactive power, set point. The power factor set point can be adjusted by a plant-level volt/var regulator, thus allowing the generators to participate in voltage control.
