Analysis and Design of a Linear Quadratic Regulator Control for Static Synchronous Compensator

Abstract

STATCOM control can improve the transmission capacity considerably and can thus enhance the transient stability margin of the power system. In this paper, an optimal control method based on linear quadratic regulator (LQR) control design for transient dynamic performance of STATCOM. The dynamic analysis is verified by transfer function simulation using Matlab and time domain simulation of the open-loop and close-loop system.
