6 FAQs about [The role of distributed photovoltaic inverters]

When do inverters disconnect a distributed PV system?

As mentioned above, current standards require that inverters disconnect the distributed PV system when grid frequency or voltage falls outside a specified range. However, inverters have the capability of “riding through” minor disturbances to frequency or voltage.

Do PV inverters monitor voltage and frequency levels?

In accordance with IEEE Standard 1547, all inverters associated with distributed PV systems continuously monitor the grid for voltage and frequency levels.

Can advanced inverters be used in the design of solar photovoltaic systems?

The use of advanced inverters in the design of solar photovoltaic (PV) systems can address some of the challenges to the integration of high levels of distributed solar generation on the electricity system.

Can a PV inverter provide voltage regulation?

A PV inverter or the power conditioning systems of storage within a SEGIS could provide voltage regulation by sourcing or sinking reactive power. The literature search and utility engineer survey both indicated that this is a highly desirable feature for the SEGIS.

How does a DPV inverter work?

A predefined power reserve is kept in the DPV inverter, using flexible power point tracking. The proposed algorithm uses this available power reserve to support the grid frequency. Furthermore, a recovery process is proposed to continue injecting the maximum power after the disturbance, until frequency steady-state conditions are met.

Can PV inverters fold back power production under high voltage?

Program PV inverters to fold back power production under high voltage. This approach has been investigated in Japan, and though it can reduce voltage rise, it is undesirable because it requires the PV array to be operated off its MPP, thus decreasing PV system efficiency and energy production.
