The Full Coverage Criterion-Based Asynchronous Power Flow Method for Integrated Transmission and Distribution Networks

Distribution networks (DNs) has more and more distributed generations (DGs), and the influence between transmission and distribution networks (T&DNs) is becoming increasingly severe. Analysis of the transmission and distribution coordination networks (TDCNs) is imperative. The forward-backward-splitting (FBS) method has the best convergence performance in asynchronous methods for TDCNs’ power flow (PF) currently, but FBS method has the defect of unreasonable convergence criteria leading to misjudgment. Therefore, this paper proposes the full coverage criterion-based (FCC) method, which achieves correct convergence judgment after full coverage of DNs’ information. The simulation results demonstrate that the convergence criterion of the proposed method is more reasonable than the FBS method.
