6 FAQs about [Distributed PV and Inverters]

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.

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.

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 inverter-tied storage systems integrate with distributed PV generation?

Identify inverter-tied storage systems that will integrate with distributed PV generation to allow intentional islanding (microgrids) and system optimization functions (ancillary services) to increase the economic competitiveness of distributed generation. 3.

How does PV affect voltage distribution?

As expected, the probability density functions shown indicate that PV causes the distribution to shift toward higher voltages, but only by a small amount. The mean point of common coupling voltages increased by less than 2 V (on a 230-V nominal base).

Does PV penetration affect distribution systems?

The potential impacts that PV could have on distribution systems has been studied extensively in the literature . The authors in have modelled a residential feeder in PSCAD and assessed the impacts of PV penetration levels up to 75% on the feeder voltage profile.
