By integrating the reactive power of the distributed generators ( DGs) with the traditional voltage regulation of the distribution network, the reactive power optimization problem in distribution power system with DGs is dis-cussed.This paper analyzed the change of the network loss when DGs access to distribution network, and established the minimum active network loss as the objective function of optimization model.A new bacterial colony optimization ( BCO) algorithm based on the basic growth and death law of bacterial colony is presented and used for solving the re-active power optimization problems of DGs in distribution network.Finally, the effectiveness of the proposed algorithm is illustrated by experiment of IEEE-33 nodes system.
