Abstract—This paper presents a new unified power-quality conditioning system (MC-UPQC), capable of
simultaneous compensation for voltage and current in multibus/multifeeder systems. The series
inverter of UPQC is controlled to perform simultaneous 1) voltage sag/swell compensation, and
2) load reactive power sharing with the shunt inverter. The active power control approach is
used to compensate voltage sag/swell and is integrated with theory of Power Angle Control
(PAC) of UPQC to coordinate the load reactive power between the two inverters. Since the
series inverter simultaneously delivers active and reactive powers, this concept is named as
UPQC. Therefore, power can be transferred from one feeder to adjacent feeders to compensate
for sag/swell and interruption. The performance of the MC-UPQC as well as the adopted control
algorithm is illustrated by simulation. The results obtained in MATLAB on a two-bus/two-feeder
system show the effectiveness of the proposed configuration.
