Research on reactive power compensation for distribution network based on biogeography-based optimization algorithm

Abstract

Distribution network reactive power optimization, which can effectively reduce distribution network wastage, can not only improve voltage distribution network quality, but also realize the distribution network security control. Stable operation provides solid foundation for the electric power enterprise economy. Unlike genetic algorithm that shares the feature information between the chromosomes, the unique migration pattern of BBO algorithm makes the good feature in the habitats broadcast widely among habitats, thus, the optimization process would be accelerated and the reactive power compensation location could be confirmed quickly. And by using BBO algorithm in the example analysis and conducting simulation through PSASP, it proves that biogeography optimization algorithm is quite effective when applied in distribution network reactive power optimization.

Development of low-voltage intelligent compensation device with high accuracy used in distribution substation

“…By using fine compensation technology with the multiple channels and small range, the refinement and precision of compensation can be ensured. The finer the compensation capacity, the more capacitors and relays there are, which inevitably increases costs and space, which is inconsistent with the current design concept of the low-voltage distribution substation [6,7].…”
