Can GFM STATCOM reduce grid voltage drop?

The proposed method is realized by the GFM STATCOM simulation platform with PSCAD/EMTDC, it is confirmed that the proposed method has a faster current limiting response speed when the voltage sag is larger, which can improve the supporting effect of GFM STATCOM for the grid voltage drop. 1. Introduction

Does grid-forming control provide stability margin and damping to WPPs?

The theoretical comparative analysis proves that the grid-forming control offers evident stability margin and damping to the WPPs especially in weak grids, superior to the grid-following STATCOM.

Does the GFM STATCOM have an Adaptive virtual impedance?

In this paper, an improved current limiting method with the adaptive virtual impedance is proposed for the GFM STATCOM. The specific implementation strategy of the GFM control is introduced firstly. The generation method of the adaptive virtual impedance and the realization of current limiting strategy are also presented in detail.

Why is GFM STATCOM important?

GFM STATCOM needs to support the output reactive current to maintain the grid voltage stability when the power grid is faulty. So, it needs to face a variety of different fault conditions, when the voltage drop is serious, it is still necessary to ensure the normal operation.

Can grid-forming converters emulate synchronous generator emulation?

New grid-forming converters can emulate the behavior of synchronous generators in terms of inertia provision and other grid services, like power-frequency and voltage-reactive regulation. Nevertheless, as a consequence of synchronous generator emulation, grid-forming converters also present angle oscillations following a grid disturbance.

What is the difference between STATCOM and GFC?

As can be seen, the GFC (upper gure) uses around 40 MW during the rst oscillation to compensate the line oscillation and the STATCOM around 20 MVar (bottom gure). Namely, in the case of line tripping the STATCOM is more effective since it exchanges less power and the damping of the line is slightly higher.
