Integration Technique

-

μG

and
APF
sh

are in parallel to grid
and placed at PCC

-

APFse

is in series

-

DC link can be connected to storage

Advantages

-

μG

can be connected to the system
during grid fault

-

μG

achieves operational flexibility in
islanding and reconnection process

-

μG

provides only the active power to
the load. Therefore, it reduces the
control complexity

-

μG

can even work in the presence of
a phase jump or a phase difference
between the grid and
μG

(UPQC

-
IR
)
.

-

Provide high quality power for all time
