Technical FAQs 4

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.

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.

What is the primary frequency regulation function of a generator set?

In order to realize the primary frequency regulation function (frequency active power droop function) of the generator set, the prime mover in the generator set is equipped with a governor.

Can photovoltaic power generation systems with different reserve capacities participate in frequency regulation?

This strategy allows PV power generation systems with different reserve capacities to participate in frequency regulation, optimizing the load reduction controller and ensuring system frequency stability. However, this strategy cannot fully utilize the frequency modulation potential of photovoltaics with different capacities.
