Power quality enhancement using unified power flow controller in grid connected hybrid PV/Wind system

摘要

This paper present amelioration power quality of hybrid power system integration with PV, wind and battery system by FACTS device. In transmission and distribution system power quality is major restraint. FACTS device have many merits in transmission like flexibility and high speed. Benefit of this system is the diverse sources can be connected to at one junction of power line, because of this these method are ascertaining to be an efficacious and ductile method for the development of the system. Harmonics produce when two diverse source connected to grid and it removed by using UPFC. The unified power flow control is the most promising device of fact family at which study in this paper is concentrated. In the study of this paper UPFC is modeled and interpretation of UPFC in a hybrid-grid connected system is examined. The extraordinary feature of the UPFC is such that it can control flow of real and reactive power as well as voltage amplitude at the same time at the UPFC nodes. The planned model is simulating in MATLAB/Simulink software.
