6 FAQs about [Weak wind field wind power generation]

Can wind power plants operate in a weak grid?

The operation of wind power plants in weak grids is increasingly challenging as the available short circuit levels are decreasing progressively and raises concerns around stable and reliable grid operation due to control interactions between inverter-based generators and rest of the grid .

Why do wind farms have a weak grid?

Notably, the weak grid condition is becoming an increasingly important concern, as wind farms are typically located far away from the utility grid. This weak integration decreases the short-circuit ratio (SCR) at the point of common coupling (PCC), precluding wind farms from being firmly supported by stable AC power systems [3, 4].

How does wind power affect a power grid?

Learn more. The proportion of installed wind power capacity in power grid continues to increase, which makes the coupled interaction between wind generators and power grid becomes more severe, then the operation characteristics of power grid during grid disturbance may change, especially in the weak grid.

Are wind farms a threat to power system stability?

As the trend of global renewable integration proceeds, the increasing wind power implementations challenge the power system stability [1, 2]. Notably, the weak grid condition is becoming an increasingly important concern, as wind farms are typically located far away from the utility grid.

How does weak integration affect a wind farm?

This weak integration decreases the short-circuit ratio (SCR) at the point of common coupling (PCC), precluding wind farms from being firmly supported by stable AC power systems [3, 4]. For example, a DFIG-based wind farm might bring stability issues when exposed to a weak grid.

How do DFIG-based wind farms work in a weak grid?

By ignoring the dynamic of stator flux, the stator voltage and the rotor voltage are decoupled. Based on physical system understanding and manual reduction, different simplified models of the grid-connected DFIG-based wind farm in the weak grid are compared with the detailed model by time-domain simulation and eigenvalues analysis.
