6 FAQs about [Can wind farm avc control energy storage ]
Why do wind farms need active voltage support?
With the steady growth of the wind power installed capacity [ 16 ], the active voltage support of wind farms to the power grid is required to ensure the stability of the connected system.
How to reduce the voltage fluctuation of PCC in a wind farm?
To suppress the voltage fluctuation of PCC caused by the wind speed variation and the load impact, the existing LRP of the wind farm is utilized first. When the reactive power reserve of the wind farm is insufficient, an active voltage coordinate control strategy is proposed to adjust the operation state of the wind farm.
What is a wind farm control strategy?
The proposed control strategy enables the wind farm to spontaneously participate in the voltage regulation of the power grid. The more complete reactive power support auxiliary services of the wind farm could be provided based on the proposed strategy. An active and reactive power coordinate control strategy of the wind farm is proposed.
Why is voltage support capacity important in a wind farm?
Considering the operation demand of the power grid with the high proportion of wind power, it is of great significance to exploit the voltage support capacity of the wind farm to the power grid to improve the reactive power environment and promote the wind power consumption of the power system.
Does DFIG-based wind farm have active voltage coordinate control?
On this basis, an active voltage coordinate control with HESS of DFIG-based wind farm is proposed to reduce the negative impact of the excessive wind speed variation and the load impact on the voltage stability of the connected system.
How does constant voltage control affect the output power of a wind farm?
When the constant voltage control is adopted only, the output active power of the wind farm increases from 0.184 p.u. to 0.634 p.u. under the wind speed variation condition, as shown via the blue line in Figure 17.
