Optimizing strategies of Transient Stability and Voltage Regulation in Multimachine Power Systems

Abstract

: The main contributions of this paper are threefold: 1) use of a STATCOM and battery energy storage procedure to enhance transient balance and furnish voltage regulation with SG and DFIG; 2) demonstrating the applying of nonlinear manipulate conception (particularly the IDA-methodology) for the design of a stabilizing suggestions controller in gigantic-scale power techniques to give a boost to transient approach efficiency; and three) establishing a methodology that can use the further levels of freedom in large-scale energy techniques with the intention to further reinforce procedure performance, in targeted the transient balance margin measured through critical clearing time (CCT)] and the dynamic transient performance of the process. In order to achieve power angle stability along with thesimultaneous regulation of frequency and voltage, the performanceof the proposed control scheme after the occurrence of large disturbances is evaluated and compared with a conventional powersystem stabilizer and a feedback linearizing controller.
