Abstract
This paper presents a comprehensive study that includes the sizing and power flow by series and parallel inverters
in a distributed generation system (DGs) that integrates the system of hybrid wind photovoltaic with a unified
power quality conditioner (UPQC). In addition to supplying active power to the utility grid, the system of
hybrid wind photovoltaic functions as a UPQC, compensating reactive power and suppressing the harmonic load
currents. Additionally, the load is supplied with harmonic-free, balanced and regulated output voltages. Since PVWind-UPQC is established on a dual compensation scheme, the series inverter works like a sinusoidal current
source, while the parallel inverter works like a sinusoidal voltage source. Consequently, a smooth alteration from
interconnected operating modes to island operating modes and vice versa can be achieved without load voltage
transients. Since PV-Wind-UPQC inverters handle the energy generated through the hybrid wind photovoltaic
system and the energy demanded through the load, the converters should be sized cautiously. A detailed study of
the flow of power via the PV-Wind-UPQC is imperative to gain a complete understanding of the system operation
and the proper design of the converters. Thus, curves that allow the sizing of the power converters according to the
power flow via the converters are presented and discussed. Simulation results are presented to assess both steady
state and dynamic performances of the grid connected hybrid system of PV-Wind-UPQC. This investigation is
verified by simulating and analyzing the results with Matlab/Simulink.
