Technical FAQs 4

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.

How synchronous generators can improve PV power generation system?

A series of characteristics of synchronous generators, such as network frequency modulation voltage regulation and inertia damping, can effectively improve the new energy PV power generation system and promote the new energy consumption.

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.

What is the maximum power of energy storage participating in grid frequency modulation?

The simulation waveform shows that under the designed control parameters, the maximum power of energy storage participating in grid frequency modulation is about 50 kW.
