In this paper convergence of the algorithm is global and gives control of the convergence conditions and rigorous theoretical proof. Keywords Flow calculation iterative learning control power system. 1. INTRODUCTION The power system flow calculation is a basic power calculation for researching power system steady state. Its task is ensure the operational status of the whole system according to the operation conditions and network structure such as the voltage on each bus amplitude and phase power distribution and power loss etc. in the network. The results of power flow calculation are the basis for computation and fault analysis of power system stability 1 . Nearly 20 years the study power flow algorithm is still very active but most research revolves around improving the Newton method and the P-Q decomposition method performed. In addition with the development of artificial intelligence theory genetic algorithms artificial neural networks fuzzy algorithm is introduced gradually flow calculation 24 . However so far these new models and algorithms cannot replace Newton s method and P-Q decomposition method 5 6 position. Due to the size of the system 7 continues to expand the power of computing speed increasing demands parallel computing technology computer .
