ABSTRACT: In this paper, the efficient population
utilization strategy for particle swarm optimization (EPUSPSO) is proposed to
solve the economic load dispatch (ELD) problem of power system. This algorithm
improves the accuracy and the speed of its convergence by changing the number
of particles effectively, and improving the velocity equation and position
equation. In order to verify the effectiveness of the algorithm, this
algorithm is tested in three different ELD cases of power system include IEEE
3-unit case, 13-unit case, and 40-unit case, and the obtained results are
compared with those obtained from other algorithms using the same system
parameters. The compared results show that the algorithm can find the optimal
solution effectively and accurately, and avoid falling into the local optimal
problem; meanwhile, faster speed can be ensured in the case.
