A new approach to ORPF (optimal reactive power Flow) based on NPSO-LRS (new particle swarm optimization, local random search) algorithm is proposed, and LRS subroutine is invoked using probability invoking strategy in this paper. The algorithm approaches and methods for solving ORPF problem are given. By applying the algorithm to dealing with IEEE 30-bus system, compared with the PSO algorithm and...
In this paper, a novel multi-objective particle swarm optimization algorithm based on adaptive niche calculation method is presented. This proposed algorithm can automatically adjust the niche radius according to the distribution of the non-dominated solutions to solve the problem that niche radius is difficult to be specified in prior when niche technique is used. In addition, a mutation operator...
