Artificial bee colony algorithm for solving economic dispatch problems with non-convex cost functions

  • 1. Unversity of Setif1

Description

Abstract:  The  main  aim  of  this  paper  is  to  propose  an  efficient  and  reliable 
algorithm to solve the economic dispatch (ED) problem with non-convex cost 
functions  in  power  systems,  using  artificial  bee  colony  (ABC)  algorithm.  For 
techno-economic  reasons  along  with  the  high  computation  time,  the  ED 
problem has undergone a significant amount of research over the last years, in 
an  effort  to  find  the  more  suitable  optimisation  algorithm  which  ensures  a 
balance  between  the  optimal  economic  contribution  of  each  generating  unit 
outputs and the required computation time. The proposed algorithm is applied 
to  different  non-convex  ED  problems,  including  prohibited  operating  zone 
(POZ)  with  ramp  rate  limits,  valve  point  effects  with  consideration  of  the 
transmission network losses and the gaseous emission of the generating units. 
Four  different  test  systems  consisting  6,  10,  15,  and  20  generating  units  are 
used to validate the consistency of the proposed algorithm to detect the optimal 
solution  for  a  given  objective.  The  simulation  results  clearly  indicate  that  the 
ABC  algorithm  provides  better  results  in  term  of  quality  solution  and 
convergence speed compared to those available in the literature. 
Keywords:  artificial  bee  colony;  ABC;  economic  dispatch;  ED;  prohibited 
operating zone; POZ; ramp rate limit; valve point effects; emission.
