Abstract	With expansion of power system, the number of nodes in distribution network increases, and higher requirements are imposed on calculation speed and convergence of power flow algorithm for distribution network. Therefore, an improved loop-current-method power flow algorithm for distribution network based on accelerated parallel LU decomposition is proposed. The algorithm uses loop current method for modeling and solving. Sparse LU factorization with column pivoting is used to solve ill-conditioned linear equations, and column elimination tree, dependent column correction relations and multi-threaded computing principles are used for power flow algorithm to accelerate parallel power flow calculation. By analyzing the cases of distribution network with different scales, it is shown that the algorithm has fast calculation speed, strong applicability and low memory usage. It has obvious calculation advantages in large scale distribution network and meets the requirements of online power flow calculation in large scale distribution network.
