6 FAQs about [Reactive power setting value of photovoltaic inverter]

How do you know if a PV inverter is reactive?

If the inverter has a kilovolt-amps (kVA) rating, Srated, equal to the active power rating of the PV module, Prated, then the reactive power capability is given by the dashed line. It is clear that, in this case, if the PV module is producing maximum active power, the inverter would not be able to inject or absorb any reactive power.

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.

Are PV inverters voltage regulated?

In the modern day, the PV inverters are being developed under the interconnection standards such as IEEE 1547, which do not allow for voltage regulations . However, a majority of manufacturers of PV inverters tend to enhance their products with reactive power absorbing or injecting capabilities without exceeding their voltage ratings.

Can reactive power be used in a PV system?

However, high PV penetration in the electricity grid is known to lead to numerous operational problems such as voltage fluctuations and line congestions, which could be eased by utilizing the reactive power capability of PV systems.

What are the advantages of a PV inverter?

The extraction of maximum power from all of the PV strings during partial shading and mismatch between PV panels. Ability to extract power from PV strings during sunrise/sunset or cloudy sky with low irradiation. Higher modularity compared to the single-stage power conversion with a central inverter.

Can reactive power control cope with significant PV generation fluctuations?

To simulate the capability of reactive power control to cope with significant PV generation fluctuations, the PV generation profile for a partly cloudy summer day was chosen. The resulting PV generation factors are shown in Fig. 4.
