This paper introduces a new concept of optimal utilization of a unified power quality conditioner (UPQC). 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...

Abstract This paper proposes a cascaded low-pass filter (CLPF) scheme for the control of unified power quality conditioner (UPQC) installed enhancing an electric vehicle (EV) charging station. With incorporation UPQC, EV station draws sinusoidal currents at unity factor and supply voltage is maintained nominal value charger input. In CLPF scheme, α–β components load current are individually pro...

ABSTRACT This paper presents a system that provides photovoltaic generation as well as the functions of a unified power quality conditioner (UPQC). The system can be controlled for current harmonics and reactive power compensation simultaneously by using a converter operating as active shunt filter. The other converter is used as active series filter and it compensates voltage harmonics or volt...
