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.

What is a hybrid STATCOM substation?

With Hybrid STATCOM technology in place, the Bolney, Ninfield and Richborough substations are now supporting National Grid’s alternating current (AC) network and enhancing regional voltage stability for the UK-Belgium HVDC interconnection, which will deliver more than 1 GW of bi-directional power between the two countries.

Does GE have a STATCOM system at Bolney Richborough & Ninfield?

“The STATCOM systems at Bolney, Richborough and Ninfield effectively demonstrates the state-of-the-art FACTS technology that GE can deliver for our global customers,” added Jullien. Historically, National Grid has counted on GE to deliver advanced technology solutions to solve complex problems.

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.

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.

What does STATCOM stand for?

This project represents the largest utility-grade Static Synchronous Compensator (STATCOM) scheme in Europe, delivering 975 Mvar power range. It is deployed and coordinated over three separate substations along the transmission network in southeast UK.
