Base station wind power supply voltage drops

Do wind turbines support grid voltage during voltage deviations?

In a power system with a high penetration of wind power generation, it is required that the wind turbines support the grid voltage during voltage deviations to ensure the system's security. After a voltage drop, the system's P – U curve is shown in Figure 2.

How is voltage stability assessed in a wind farm?

The voltage, reactive power and active power of each bus in the system are collected for voltage stability assessment. The capacity of the wind farm is 200 MW and the power factor is set as 0.99. The power flow analysis results and voltage diatribution of the test can be demonstrated in Fig. 4, Fig. 5, respectively. Fig. 3.

Can new energy sources improve the voltage stability of grid-forming wind power systems?

The aforementioned research findings are useful for enhancing the voltage stability of power grids with new energy sources, but the transient voltage response of grid-forming wind power systems and parameter ranges lack a theoretical design basis.

Why do wind turbines cause voltage instability?

Wind turbines might not be able to provide sufficient reactive power support owing to the technology employed and the limited capacity of the grid to transmit power, leading to voltage instability. In addition, the intermittent nature of wind power and the limited fault response also contribute to voltage and system instability.
