A new method of power network planning based on improved ant colony algorithm is presented. For a given power network model
once establishing initialization pheromone matrix
searching the path depending on the special ability of ant colony
combining with an improved method of refreshing pheromone
Manhattan distance and the thought of flexibility
the best power distribution network planning path is found at a higher rate only if it exits. Some examples confirm the computing efficiency and global convergence to solve the difficulty of the premature convergence due to repeat calculation in the existing ant colony algorithm.
