6 FAQs about [Photovoltaic inverter island test capacity]

Are photovoltaic inverters effective in detecting island conditions?

Several methods for identifying island condition have been proposed, both passive and active, each one characterized by its pros and cons. The standard IEC 62116 was promulgated with the aim of regulating a test procedure to evaluate the IP effectiveness of PhotoVoltaic (PV) inverters independently from the island detection method implemented.

Do utility-interconnected photovoltaic inverters have islanding prevention measures?

Utility-interconnected photovoltaic inverters - Test procedure of islanding prevention measures IEC 62116:2014 provides a test procedure to evaluate the performance of islanding prevention measures used with utility-interconnected PV systems.

How are PV inverters tested?

Three PV inverters from different manufacturers were used in testing. The tests employed an RLC load bank tuned so that the island circuit: matched the real and reactive power of the inverters under test.

How are multi-inverter Island scenarios tested?

The multi-inverter island scenarios were tested using a ten realistic distribution circuit topologies with the inverters connected to different points in those circuits. A detailed test plan was used to empirically identify worst-case test scenarios for in-depth anti-island testing.

What is photovoltaic distributed resource islanding?

In photovoltaic distributed resource islanding, one or more non-utility generation sources (more specifically, sources over which the utility has no direct control) and a portion of the utility system operate while isolated from the remainder of the utility system. Many methods for detection of the islanding condition have been used.

Do multi-inverter Islands increase island duration?

In summary, for the islanding detection philosophies represented in the inverters tested, this report found evidence that performing voltage and frequency ride-through prolongs island duration for single inverters, but did not find evidence that multi-inverter islands necessarily increase that duration further.
