Research on integrated calculation method of theoretical line loss of MV and LV distribution Network based on Adaboost integrated learning

Abstract

Aiming at the problems of system and index dispersion of line loss assessment in MV and LV distribution network, this paper proposes a integrational theoretical line loss calculation method of MV and LV distribution network based on rough set and Adaboost. The influence factors of theoretical line loss of medium and low voltage distribution network are analyzed from three aspects: network structure, operation characteristics and equipment characteristics. Combined with rough set theory, the influence degree of each influencing factor on theoretical line loss was calculated, and the characteristic parameters of model training were selected based on this. Finally, based on integrated adaboost learning algorithm, the integrated theoretical line loss calculation model of MV and LV distribution network is constructed. The calculated theoretical line loss can provide unified line loss assessment index for daily line loss management of MV and LV network, simplify line loss management workflow, optimize operation and maintenance resource allocation, and then improve line loss management efficiency of MV and LV distribution network.
