6 FAQs about [Primary frequency regulation of photovoltaic energy storage project]

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.

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.

How does a PV system participate in frequency regulation?

Hence to enable PV to participate in frequency regulation it is to be de-loaded so that a portion of power output is available for frequency regulation. In order for a PV system to provide the fast-acting response, it needs to maintain active power reserve and change the power output in response to the frequency deviation.

Can a battery energy storage system support primary frequency regulation?

Author to whom correspondence should be addressed. This paper proposes a strategy for sizing a battery energy storage system ( BESS) that supports primary frequency regulation ( PFR) service of solar photo-voltaic plants. The strategy is composed of an optimization model and a performance assessment algorithm.

Can PVPP participate in power system frequency regulation?

Scholars at home and abroad have successively proposed power reserve control of photovoltaic power generation, virtual synchronous machine technology , etc. Ref. proposes a method that combines inertia evaluation and active power reservation, so that PVPP can participate in power system frequency regulation.

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.
