Comparative study of battery-based STATCOM in grid-following and grid

Recently, as an alternative to GFL-STATCOM, the grid-forming (GFM) control has been widely discussed since it well fits to the weak grid conditions [5]. Differing from the GFL current source features, the GFM operates as a voltage source to support WPPs, meanwhile synchronizing by active power control [6], rather than PLL in GFL.

5 FAQs about [Grid forming statcom Haiti]

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 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.

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 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 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.
