The conventional backward/forward sweep method, used for solving the load flow, is only applicable to radial systems. A new load flow method is proposed in this report for islanded droop-controlled meshed AC microgrids, where the backward/forward sweep (BFS) method is proposed in conjunction with a loop-breaking approach to determine the power flows for meshed micro-grids. The proposed approach is applied to the 33-bus test system, and the recorded results are validated with simulation results obtained from PSCAD/EMTDC software. These recorded results confirm that the proposed method is accurate, and it can be used as a tool in the analysis and planning of meshed microgrid systems.
