دانلود Distributed Multi -Agent System Based Load Frequency Control for Multi- Area Power System in Smart Grid

Abstract

This  paper  presents  an  intelligent  controller  for  “Load  Frequency  Control  (LFC)”  application  in  “smart  grid (SG)”environment having changes in communication topology via  multi  agent  system  (MAS)  technology.  In  study,  network  induced  effects,  time  delay  and  change  in  communication  topology  (CT)  have  been  addressed  to  examine  the  system  performance in closed loop. An event triggered control method  is  used  to  reduce  the  communication  burden  in  a  network. An intelligent controller based on reinforcement learning  consists  of  two  levels  estimator  agent  and  controller agent  in  each  multi-area  system.  Particle  swarm  optimization )PSO) is used to tune the controller parameters. Further proposed control strategy and system architecture as MAS for LFC  in  smart  grid  is  analyzed  in  detail,  verified  for  various load conditions and different network configurations. In addition, mean square error of power system states with CT is also analyzed. The results of this study validate the feasibility of  the  proposed  control,  as well  as  the  capability  of  the  MAS  for the operation of LFC in SG with changes in CT.
