6 FAQs about [Grid forming statcom Bahamas]

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.

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 STATCOM operate in GFM mode?

A novel conclusion drawn from the comparative analysis is – the STATCOM operates in GFM mode can broaden the stability margin of WPPs effectively in comparison with GFL, which holds true in different grid conditions and control parameters specified in the research. The conclusions are finally proved by the simulation results. 2.

Does alternating voltage control of Statcom benefit from GFM mode?

This conclusion holds true for most conditions with properly designed parameters, including different bandwidths of the alternating voltage control of STATCOM in 1∼10 Hz and phase-locked loop of grid-following STATCOM ranging from 5 to 100 Hz, which is benefited from the sufficient stability margin of GFM mode.

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.
