Unified power flow controller (UPFC) integrated with electromagnetic energy storage system for system stability enhancement

摘要

In this paper analysis the UPFC integrated with energy storage devices for improvement of system stability compensation. Before that, used traditional UPFC is to control all transmission line parameters simultaneously or selectively but don't have appropriate control for throughout system. During large transients; traditional UPFC have restricted capability of power flow control. In this paper to do reduce or eliminate that negative aspect of established UPFC using substantial energy storage devices adapted with UPFC. In this proposed system Integration of Superconducting Magnetic Energy Storage (SMES) into UPFC is described. SMES is connected to UPFC through an interface with DC-DC chopper. UPFC with SMES system will inject or absorb real and reactive power to or from an influence system at really quick rate on a repetitive beginning of stability problem. Here Comparative Analysis of the two types, one is integration of electromagnetic energy storage into UPFC and another is integration of electrochemical energy storage into UPFC is done by means of MATLAB/SIMULINK software package.
