6 FAQs about [Photovoltaic power inverter grid exceeds limit]

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.

How to provide voltage support in PV inverter?

To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.

Do SolarEdge inverters support advanced grid limitations?

To improve grid stability, many electric utilities are introducing advanced grid limitations, requiring control of the active and reactive power of the inverter by various mechanisms. SolarEdge inverters with CPU version 2.337 and later support these requirements (some features may require later versions; refer to the relevant feature for details).

How to reduce the voltage limit of a photovoltaic inverter?

In the literature [7, 8], it proposes to reduce the voltage limit by reducing the output active power of the inverter. Although this method can effectively solve the problem of dot voltage limit, it increases the photovoltaic discard rate.

Are control strategies for photovoltaic (PV) Grid-Connected inverters accurate?

However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.

How to ensure maximum exploitation of the inverter capacity?

To provide overcurrent limitation as well as to ensure maximum exploitation of the inverter capacity the performance of the proposed control strategy, is evaluated as per the three generation scenarios given below: In this case, the inverter’s capacity is majorly exploited through the injection of active power under normal operating condition.
