Given a symmetric closed monoidal category $V$, a $V$-enriched category $A$ with underlying ordinary category $A_0$ and a subcategory $\Sigma$ of $A_0$ containing the identities of $A_0$, H. Wolff defines the corresponding theory of localizations.

While Wolff in principle defines localizations more generally, most of the theory is developed for reflective localizations, i.e. when the counit of the 2-adjunction is iso of $V$-categories. For such a $V$-enriched category $C$,

consider reflective $V$-localizations which preserve finite limits of the enriched category of presheaves $[C^{op},V]$, and relate them to an enriched version of Grothendieck topology on $C$, and to a “universal closure operation” on $[C^{op},V]$. See also under enriched sheaf.
