Current moment-based method for dynamic reconfiguration research in distribution network

Considering the energy-based calculation and analysis of the radial network and the mean value theorem for integrals,the concept of the median current moment is presented and the power flow model based on this concept is established accordingly.The energy-based loss theorem is verified.This theorem transfers the problem of energy-based,time-oriented integrals into that of the median current moment,which lays the foundation of network loss calculation based on electricity energy.Based on the concept and model above,the median current moment method is developed for dynamic reconfiguration in distribution network.This method transfers the dynamic reconfiguration problem into the static median reconfiguration based on median current moment,which simplifies the computation process.Simulation results testify the validity of this method.
