Hybrid Artificial bee Colony Algorithm Based on Gradient Method for Optimal Power Flower Calculation System

Aiming at optimal power flow calculation problem in power system,this paper presents a new method of hybrid artificial bee colony algorithm based on gradient method GABC.Firstly,the new algorithm used quickness searching of gradient method to obtain a local minimum,then by utilizing the abilities of global searching of artificial bee colony algorithm,it escaped from trapping this local minimum.At last,the global minimum was achieved through iterative computation.Simulation experiments of IEEE5 system show that the improved algorithm can be better dealt with optimal flow constraints in dealing with the issue of optimal power flow.This method can also find preferable results and its correctness and validity is proven by a series of tests and computation,and that the algorithms can be widely applied to the areas of power system planning and operation.
