6 FAQs about [Photovoltaic power station inverter frequency]

Can photovoltaic systems support grid frequency regulation?

Previous studies have proposed an active power control of photovoltaic systems to support grid frequency regulation in two different forms, namely slow frequency control that facilitates load frequency control and fast frequency that facilitates synchronous generator inertial response control.

How does a PV inverter regulate the voltage?

To regulate the voltage of the system, the system operator specifies the droop coefficient. The simplest mode of operation is power factor mode, in which the inverter injects or absorbs reactive power to maintain a specified power factor at the PCC. A fixed reactive power reference is specified for the PV inverter in the reactive power mode.

Can a solar PV plant participate in frequency and voltage control?

A comprehensive control strategy for a utility-scale solar PV plant is proposed to simultaneously participate in frequency and voltage control without the aid of any energy storage. The frequency response is accomplished by maintaining some active power reserves that enable the PV plant to participate in both over- and under-frequency events.

What is a fixed reactive power reference for a PV inverter?

A fixed reactive power reference is specified for the PV inverter in the reactive power mode. Photovoltaic systems tied to the distribution system typically use power factor and reactive power operating modes, whereas PV systems connected to the transmission system employ voltage control mode [ 48 ].

What is a PV inverter?

As clearly pointed out, the PV inverter stands for the most critical part of the entire PV system. Research efforts are now concerned with the enhancement of inverter life span and reliability. Improving the power efficiency target is already an open research topic, as well as power quality.

Can a PV system participate in frequency control?

Recent studies have suggested that in order for the PV system to participate in frequency control, some active power reserves must be maintained by operating at a lower power level than the maximum output. This will enable effective up-and-down control of their output and enable them to operate in a grid friendly manner.
