Photovoltaic power station power generation frequency

Are photovoltaics involved in primary frequency regulation?

Since the frequency of the power system always keep changing, the participation of photovoltaics in primary frequency regulation is time-sensitive. Although many countries have set standards on the response time of photovoltaic frequency regulation, the requirements of these standards are very loose.

What factors affect the active frequency support capability of PV power stations?

According to the results shown in Fig. 6, the key indicators that affect the active frequency support capability of PV power stations are the active power reserve capability, the response time and regulation time of the frequency response process.

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.

Does data communication delay affect primary frequency regulation of photovoltaic power plants?

With the large-scale development of photovoltaic power generation, photovoltaic power plants (PVPP) are required to participate in primary frequency regulation to maintain the stability of the power system. Existing researches seldom consider the influence of the data communication delay of PVPP on the primary frequency regulation ability of PVPP.

What is active frequency support capability (AFSC) of PV stations?

With the increasing penetration of photovoltaic (PV) in power grid, to cope with the deteriorating frequency security of the system, PV stations are required to participate in frequency regulation by grid codes. Knowing the active frequency support capability (AFSC) of PV stations is essential for strategy design of frequency response.

Do PV systems participate in primary frequency regulation?

From the perspective of control strategies, the participation of PV systems in primary frequency regulation can generally be categorized into two types: load reduction control and coordinated control with PV-energy storage systems.
