| Abstract: | Based on real time measurement data and normalized history load data of distribution system,load active and reactive power are used as genes,probability model of user load and load restriction in distribution system are considered in gene coding and fitness function.Seravel gene manipulations are used to get solution combinatorially.The algorithm is proved feasible by IEEE typical examples,calculation precision and velocity could satisfy the demand of state estimation in distribution system. |
