主 题：Photovoltaic wind turbine unified power quality conditioner power flow distributed generation system
摘 要：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 ***,the load is supplied with harmonic-free,balanced and regulated output *** 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 ***,a smooth alteration from interconnected operating modes to island operating modes and vice versa can be achieved without load voltage *** 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 ***,curves that allow the sizing of the power converters according to the power flow via the converters are presented and *** results are presented to assess both steady state and dynamic performances of the grid connected hybrid system of *** investigation is verified by simulating and analyzing the results with Matlab/Simulink.
