5 FAQs about [Croatia grid forming statcom]

How stable is a wind power plant with Statcom in grid-following and grid-forming modes?

The stability behaviors of wind power plant with STATCOM in grid-following and grid-forming modes are compared. Grid-forming STATCOM provides more stability margin to wind power plants than grid-following STATCOM. In weak grids, grid-forming STATCOM gives a nearly tenfold rise in damping ratio to wind power plants in comparison with GFL control.

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.

Is GFL-STATCOM stable if grid strength decreases?

Please notice, although SCR=2 at WT terminal is a weak grid condition, the grid is still strong for the STATCOM due to its onshore location and capacity limit. It is therefore predictable that the stabilizing effects of GFL-STATCOM will not be satisfactory as grid strength reduces. Fig. 10.

Is GFM-STATCOM suitable for weak grid stabilization of WPP?

As for GFM in case III, it not only provides sufficient stability margins in all conditions, but also showcases an interesting opposite behavior as GFL, i.e., the stability is enhanced as SCR reduces in this certain range, which makes GFM-STATCOM especially suitable for weak grid stabilization of WPP.
