要約(日本語): This paper presents the formulation and the solution of the distribution power flow based on the backward/forward sweep method. An improved backward/forward sweep power flow method is developed that can be employed for accurately solving the nonlinear power flow problem. The main idea of proposed method is to determine a possible solution for each branch in the studied distribution system by employing efficient quadratic equations. Comprehensive comparisons have been made between the proposed improved method and two other commonly used backward/forward methods. Intensive test results demonstrate that the proposed distributed power flow method is superior in terms of computations speed and convergence characteristics when compared with the two other methods.
