Yes, I'm aware of locations where this is not only in use, but in some instances required.
The Ivaco steel mill near Longueuil, Ontario, Canada, which to my understanding employs arc furnaces, uses this to stabilize the voltage on the 230 kV system that supplies it. Whenever the system is for some reason not in service, numerous voltage complaints are received from customers fed by two adjacent transformer stations on the same 230 kV corridor.
Ameristeel in Oshawa, Ontario, also fed at 230 kV, has a flicker compensator that must be in service whenever the mill is in production; this mill was causing so many issues for neighbouring customers that this mandatory stipulation was put in place.

Alas, I am now retired, and no longer have any access to information about these schemes; I'm only able to pass along what I remember about them.
I'm not fully informed as to their status worldwide, but from what I've seen, actual synchronous condensers [SC] are becoming quite rare; to my knowledge, for the most part only utilities and governments have the fiscal clout to spend the kind of capital needed to install them and the OM&A budget to run them.
I do recall one transformer station in northwestern Ontario that had [at the time of my retirement a year and a half ago], and presumably still has, both a synchronous condenser and an SVC; I ended up being the person pushing for the development of an operating protocol for how to share the local reactive demands satisfactorily between these two machines, whether boosting or bucking.
Where industries with electric arc furnaces are forced to spend their own money in order to continue operating, they generally acquire their own Static Var Compensator [SVC] and harmonics mitigation schemes so as to satisfy the requirements of the local Authority Having Jurisdiction [AHJ].
Have you done an internet search on "electrical flicker compensator compensation"? I just did, and there appeared to be several links to technically expansive articles or pages.
