As for the shortcoming of traditional genetic algorithm which can easily fall into partial optimum and have slow rate of convergence when used in solving the reactive power optimization problems of distribution network

in this paper

adaptive genetic algorithm is introduced into reactive power optimization of distribution network

adaptive cross rate and variation rate is used so to make them conform to the dynamic and adaptive genetic algorithm search process.Some improvements in such areas as encoding

fitness function design

genetic operations and termination criterion are made.IEEE 33 test system is used for simulation analysis and the usefulness and effectiveness of the algorithm is shown in the numerical example.
