Use of Particle Swarm Optimization in the computation of an optimal permittivity distribution in functionally graded material insulators

Promising functional graded materials for compact gaseous insulated switchgears/pipelines

“…The PSO method has the advantages of simple concept, easy realisation with only a few tuning parameters and so on. In 2015, Qasim and Gupta [42] introduced the PSO method to modify the spatial distribution of the permittivity in a spacer. The optimisation objective is shown as follows and was solved by the PSO algorithm…”

“…The PSO method has the advantages of simple concept, easy realisation with only a few tuning parameters and so on. In 2015, Qasim and Gupta [42] introduced the PSO method to modify the spatial distribution of the permittivity in a spacer. The optimisation objective is shown as follows and was solved by the PSO algorithm where E i is the E‐field of polygon i in and around the insulator; E j is the E‐field of node point j inside the insulator; ɛ is a vector of permittivity values of polygons inside the insulator; and wgt is a weighing factor.…”
