Power quality problems have become more complex at all level of power system. The power electronic based power conditioning devices can be the effective solution to improve the quality of power supplied to the distributed system. UPQCis custom power device, designed to compensate both source current and load voltage imperfections. In this paper the design of combined operation of unified power quality conditioner and a hybrid power generation is proposed. The proposed system is composed of series and shunt inverters, PV array and WECS connected to DC link which is able to compensate the voltage sag, swell, harmonics and voltage interruption. The proposed system is able to inject the active power to grid in addition to its ability in improvement of power quality in distribution system. The performance of the proposed UPQC system is validated through simulations using MATLAB/SIMULINK.

Abstract


Power quality problems have become more complex at all level of power system. The power electronic based power conditioning devices can be the effective solution to improve the quality of power supplied to the distributed system. UPQCis custom power device, designed to compensate both source current and load voltage imperfections. In this paper the design of combined operation of unified power quality conditioner and a hybrid power generation is proposed. The proposed system is composed of series and shunt inverters, PV array and WECS connected to DC link which is able to compensate the voltage sag, swell, harmonics and voltage interruption. The proposed system is able to inject the active power to grid in addition to its ability in improvement of power quality in distribution system. The performance of the proposed UPQC system is validated through simulations using MATLAB/SIMULINK.
