This paper explores different strategies to set
the reference current of a STATCOM under unbalanced
grid voltage conditions. The aim of the proposed control
strategies is to provide a set of reactive current references to
be injected by the STATCOM under unbalanced grid faults.
Their performance, as well as their grid support capability
will be evaluated by means of simulations. Finally, the
experimental response will be tested in a low-scale setup, in
order to verify and validate their dynamic performance and
steady state response.
