6 FAQs about [Photovoltaic inverter primary frequency regulation bidding]

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.

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.

Do photovoltaic power plants support frequency regulation?

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 can inverters improve the frequency regulation ability of PVPP?

The longer the delays, the weaker the PVPP’s ability to participate in primary frequency regulation. In addition, the optimization of PVPP communication system and control strategy of inverters can help improve the frequency regulation ability of the PVPP, thereby maintaining the frequency stability of the power system. 1. Introduction

How does a PV system participate in frequency regulation?

The PV is participated in frequency regulation by modifying the modulation index in response to the frequency deviation. In a 1.2 kW PV system the proposed scheme was validated where only 3% of the PV output is modulated. Fig. 16 shows the control block of the modulated PV system, where the ramp rate limiter controls the PV output within 50 W/min.

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 .
