A new continuation power flow method is proposed, which is an extension of the popular backward/forward sweep power flow (BFS) for distribution network. The different reasons for the divergence of Newton's algorithm and fixed‐point iteration algorithm near the saddle node bifurcation point have been investigated extensively. Loop‐analysis‐based power flow (LBPF) is a revised version of BFS, which belong to fixed‐point iteration algorithm and its convergence remains satisfactory in a meshed network. Based on LBPF, a tailored continuous power flow method is developed, which can be used as a voltage stability analysis tool for both radial and meshed distribution networks. Numerical test results are presented to validate the proposed procedure.
