6 FAQs about [Grid forming statcom Mayotte]
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 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. Fig. 11.
How does a STATCOM control a microgrid?
The STATCOM is controlled so that the DC side voltage is always maintained at the rated value. The voltage magnitude of STATCOM is adjusted in the synchronous (qd) reference frame to adjust the microgrid voltage and the RP exchanged between the STATCOM and the microgrid.
Why do we need a battery for STATCOM in GFM mode?
The batteries make it possible for STATCOM in GFM mode with the active power-dependent ancillary services, e.g., frequency response. All studies hereafter are based on the STATCOM with batteries installed at dc-link as shown in Fig. 1.
