6 FAQs about [Photovoltaic inverter voltage regulation method]

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.

How does an inverter regulate voltage levels in a utility grid?

The proposed novel method enables an inverter to inject the required level of reactive power to regulate the voltage levels of the utility grid within specified limits. In the process, the inverter does not absorb active power from the grid for its internal operation.

How to ensure Voltage Security in photovoltaic distribution systems?

In this Letter, a novel voltage regulation method is proposed for ensuring voltage security in photovoltaic (PV) distribution systems. It is a two-level regulation to reduce overall voltage deviation (VDE) and voltage difference (VDI). Firstly, evaluation indexes for VDE and VDI are built.

How to optimize the efficiency of PV inverters?

Different from the voltage regulation method according to V-Q curve, here, the PAO strategy is executed to coordinate the V-Q curve slopes of all inverters to maximize the active power output of PV, thus the efficiency of DGs can be improved. The contributions of this paper are summarized as follows.

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.

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 .
