6 FAQs about [Adjustment of photovoltaic power station support]

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

How do PV inverters control stability?

The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability . In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. .

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.

How is PV power generation affecting control performance & stability?

PV power generation is developing fast in both centralized and distributed forms under the background of constructing a new power system with high penetration of renewable sources. However, the control performance and stability of the PV system is seriously affected by the interaction between PV internal control loops and the external power grid.

How a PV power station can absorb reactive power during HVRT period?

During the HVRT period, firstly, the PV power station should absorb a certain amount of reactive power in order to make the voltage at PCC become lower. Also, the amount of reactive power the PV power station can absorb is decided by the capacity of PV inverters. The active power which the PV inverter generated should not be changed.

How can a photovoltaic energy storage system provide efficient frequency support?

To ensure that the photovoltaic energy storage system provides efficient frequency support and power oscillation suppression, the virtual inertia and virtual damping parameters of the VSG should be coordinated based on system frequency safety and damping ratio constraints.
