6 FAQs about [Photovoltaic inverter reactive power regulation mode]
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 grid-connected PV inverter control overvoltage and undervoltage?
Generally, a grid-connected PV inverter can be programmed to inject and absorb the reactive power. Hence, both the overvoltage and undervoltage conditions can be regulated using the reactive power control ability. The dq components theory, which will be described in Section 2, can be used to perform the controlling mechanism efficiently .
