Furthermore, the Sunny Island will respond to voltage fluctuations with reactive cur-
rent in droop mode. Thus, only an average cos
φ
of 1 will be reached. Temporarily, it
will deviate from this value.
In such systems further grid-forming elements (e.g. gensets) can only then be con-
nected if these are capable of automatically synchronizing themselves to the grid and
have a droop characteristic. However, for some common system structures the
Sunny Island provides functions to synchronize the system to the genset, even in
droop mode.
