6 FAQs about [Frequency selection principle of photovoltaic bracket]

Can a grid-connected solar photovoltaic system participate in primary frequency regulation?

Conclusion This paper proposes a fuzzy-based control strategy for the grid-connected solar photovoltaic system to participate in primary frequency regulation without any energy storage support. A combined fuzzy based de-load control and control mode selector was proposed to enable PV operation at a scheduled level of power reserve.

What is a new frequency control strategy based on a PV system?

A new frequency control strategy based on the PV system being forced to participate in the inertial response by moving its operating point away from the maximum power point only when the inertia of the system is unsatisfactory to process the initial frequency excursion .

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.

How does a PV system participate in frequency regulation?

The PV system connected to the network can participate in frequency regulation during the positive frequency excursion, increasing the frequency of the system due to higher than load generation, by reducing the production of PV.

What are the different types of frequency regulation methods for photovoltaic power generation?

At present, there are two main types of frequency regulation methods for photovoltaic power generation. One is to operate at the maximum power point, and release or absorb active power through energy storage equipment, so as to provide support inertia for the system to participate in frequency regulation.

Can centralised photovoltaic power generation provide inertial response and primary frequency control?

In [ 19 ], an operation and control strategy based on centralised photovoltaic power generation was proposed that can provide inertial response and primary frequency control to support the black start of large capacity power systems.
