SLIDING MODE CONTROLLER DESIGN FOR UPFC POWER LINE CONTROL COMPENSATION DEVICE

Abstract

In recent years, power flow control has become increasingly important in the
field of intelligent power transmission systems. The Unified Power Flow Controller
(UPFC) provides real-time control of active and reactive power flows. This article
presents the results of synthesizing a sliding regulator (SMC) for a power flow
control compensation device (UPFC). The controller has helped stabilize grid
capacity, reducing the influence of nonlinear loads and harmonic phenomena on
grid stability. The quality of the proposed controller is evaluated through
simulation results of the 500kV power grid transmission system using Matlab-
Simulink software.
