6 FAQs about [Use of distributed photovoltaic inverter]

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 to choose a photovoltaic inverter?

The inverter of the photovoltaic power generation system should have the ability to adjust the power factor within the range of 0.95 leading to 0.95 lagging. If necessary, it should have the method predetermined by the State Grid Corporation, according to the voltage of the grid connection point within its reactive power output range.

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.

Do distributed photovoltaic systems contribute to the power balance?

Tom Key, Electric Power Research Institute. Distributed photovoltaic (PV) systems currently make an insignificant contribution to the power balance on all but a few utility distribution systems.

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.

What are the benefits of a PV inverter?

Use energy storage. PV energy could be diverted from the utility line to a storage medium for later use when voltages are too high. The many benefits of energy storage are described elsewhere in this report. Use nonunity power factor operation to give PV inverters voltage control capability.
