In order to improve the convergence speed of the distribution system, and combine the constant character of the voltage of the root node, this paper puts forward a method, in which we can deduce the formula from the beginning known voltage and computing power to the terminal. And we use the K th new voltage value when circularly deducing the terminal voltage. This method improves the convergence speed that is always low in routine branch current method. This paper also uses a local searching and replacing method which increases the diversity of the individual, and at the same time accelerates the elimination of the individual which has low fitness value to improve the average fitness value of every generation, and remarkably improve the convergence speed of the GA. Computations of practical examples with 120 nodes and 53 nodes illustrate this method to be correct and efficient.
