POWER SYSTEM STABILIZATION USING ANN CONTROLLED STATCOM-SMES

Abstract

An Static Compensator integrated with Superconducting magnetic Energy Storage (SMES) device using Artificial Neural Network (ANN) controller to stabilize the Single Machine Infinite Bus (SMIB) system is proposed in the present work. The active power exchanged by SMES plays a major role in improving the dynamic performance of power system during changes in operating conditions. The application of ANN controller enhances the performance of STATCOM-SMES system significantly. The use of PI controller to control the rate of active power exchange between a power system and superconducting coil of STATCOM-SMES has been reported already. In the present work, PI controller is replaced by artificial neural network controller. The dynamic performance of STATCOM-SMES in term of power system stabilization, using ANN controllers is evaluated through the simulation by using SimPowerSystems of SIMULINK/MATLAB.
