6 FAQs about [Photovoltaic inverter requirements]

Are photovoltaic inverters able to meet der requirements?

Initial indications show that, in general, photovoltaic (PV) inverters are able to fulfil both the static and the dynamic requirements. Besides the new requirements of the guideline, an extensive certification process for DER units and plants has also been introduced.

What are the requirements for a power inverter?

Inverter should meet the requirements specified in IEEE Std. 929-2000 or other national standard or the interconnecting utility requirements. Phase current imbalance should be less than 5% measured at 50% and 100% rating. Unbalanced phase currents may cause overheating of the utility transformer.

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.

Do I need a PV generator for a DC inverter?

Using a PV generator is not mandatory for the supply of the PV inverter at the DC terminals, since FGW TR3 states that module-independent tests are sufficient for the determination of the behaviour on the AC side.

Do PV inverters meet the new BDEW MV guideline?

Initial tests have revealed that PV inverters are generally capable of satisfying the static as well as the dynamic functionality requirements of the new German BDEW MV guideline, in terms of supporting network operation and stability.

How can a PV inverter be used in a utility system?

Integrate PV inverters into utility supervisory control and data acquisition systems or AMI systems. Inverters could be tied into utility communications systems, which would issue a warning to inverters in sections of the utility isolated from the mains. Any available channel, such as BPL, DSL, or coax, could be used.
