6 FAQs about [The working process and principle of solar container frequency regulation]

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.

Why do PV systems need a primary frequency response (PFR)?

During system imbalance, PFC is not sufficient to limit the frequency excursion due to reduced inertia. To cope with frequency stability challenges, PV systems are required to provide sufficient primary frequency response (PFR) and participate in frequency regulation to reinforce grid security.

How do PV systems cope with frequency stability challenges?

To cope with frequency stability challenges, PV systems are required to provide sufficient primary frequency response (PFR) and participate in frequency regulation to reinforce grid security. Table 2.

How can battery energy storage systems improve frequency response?

However, with more solar and wind power integrated into the grid, the system’s ability to stabilize frequency declines. To address this challenge, Battery Energy Storage Systems (BESS) are now playing a critical role in delivering fast, precise frequency response services.

What is frequency regulation in electric power system?

Frequency regulation in the electric power system consists of primary control, secondary control or automatic generation control (AGC) and tertiary control . Primary frequency consists of two subparts inertial response and governor response.

Does power fluctuation affect the frequency regulation mechanism of large scale PV units?

Major utilities will enforce stringent regulations in operating large scale PV units in future. Therefore, the power fluctuation of large scale PV units must be limited; otherwise it produces potential reliability impact on the system frequency regulation mechanism.
