6 FAQs about [High frequency protection setting value of photovoltaic inverter]

How do PV inverters support grid frequency?

Grid frequency support is achieved by adjusting inverter real power output. This functionality is limited with PV inverters because the inverters are following the DC energy provided to them by the sun. For a grid high frequency event, PV inverters can be easily set to reduce active power to help reduce the grid frequency.

Can FRT be disabled in a PV inverter?

FRT can also be disabled resulting in inverter tripping during grid voltage or frequency excursions. Grid frequency support is achieved by adjusting inverter real power output. This functionality is limited with PV inverters because the inverters are following the DC energy provided to them by the sun.

Why should you invest in a PV inverter?

The advanced robust control will able to manage the grid-friendly features, that will be integrated into inverters to support grid voltage and frequency regulation, contributing to grid stability in regions with high PV penetration.

What happens if a PV system has a high switching frequency?

The current flows through the inverter, filter, and grid, and then returns to the PV generation side through a ground path that may exist without galvanic isolation. High switching frequency may result in high frequency common-mode voltage as well as a high amount of common mode current, that exceeds grid standards allowable values.

Do photovoltaic power plants support frequency regulation?

Jibji-Bukar, F., Anaya-Lara, O.: Frequency support from photovoltaic power plants using offline maximum power point tracking and variable droop control. IET Renew. Power Gener. 13 (13), 2278–2286 (2019) Rajan, R., Fernandez, F.M.: Impact of distributed virtual inertia from photovoltaic sources on frequency regulation in hybrid power systems.

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.
