Abstract
This paper introduces a new method for solving the distributed ac power flow (pf) problem by further exploiting the problem formulation. We propose a new variant of the aladin algorithm devised specifically for this type of problem. This new variant is characterized by using a reduced modelling method of the distributed ac pf problem, which is reformulated as a zero-residual least-squares problem with consensus constraints. This pf is then solved by a Gauss-Newton based inexact aladin algorithm presented in the paper. An open-source implementation of this algorithm, called rapidpf+, is provided. Simulation results, for which the power system's dimension varies from 53 to 10224 buses, show great potential of this combination in the aspects of both the computing time and scalability.
