In order to improve the efficiency of the existing reactive power scheduling algorithm and solve the problem that the model is prone to fall into local extremum,a model based on the improved artificial bee colony algorithm is proposed.An objec-tive function of reactive power scheduling is established to minimize the actual power loss,voltage deviation and voltage stabili-ty enhancement under the constraints of equality and inequality.An improved artificial bee colony algorithm based on neighbor-hood radius selection is proposed,and a new neighborhood selection mechanism and an improved search strategy are designed.In the experimental stage,the IEEE39 bus power system is taken as an example to verify the effectiveness and efficiency of the proposed algorithm.Compared with linear programming(LP),particle swarm optimization(PSO)and basic artificial bee colo-ny(ABC)algorithm,the improved ABC algorithm has better execution efficiency and higher solution quality than other algo-rithms.This model provides a reference for the development of power dispatching and stable operation of distribution network.
