6 FAQs about [The photovoltaic inverter has no response when there is voltage]
What is reactive power response in a PV inverter?
Specifically, the inverter’s reactive power response to PV power variations in different phases is adaptively scheduled in order to avoid adverse effect of inter-phase Voltage-Reactive Power interaction on voltage regulation.
When should a PV inverter limit the power output?
This should limit the power output of a PV system when the inverter experiences a quick surge in its power output. Besides, it could uniformly limit the power output during the lead time prior to the occurrence of an expected drop.
What happens if a PV inverter is unbalanced?
With unbalanced PV power integration, traditional methods without an inter-phase coordination design may cause concerning high voltage on one phase. As a result, PV inverters installed on this phase are exposed to overvoltage problems and disconnection risks.
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 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 PV inverters work without inter-phase coordination?
Without the inter-phase coordination design, PV inverters are only expected to mitigate overvoltage problems of their own phase through absorbing reactive power. As shown in Fig. 10 (b), all PV inverters operate with lagging power factors (absorb reactive power) during the noon time when overvoltage problems are most likely to occur.
