要約(日本語): Interconnection of the distributed generators (DG) to the power system causes the efficiency degradation of distribution system management. Minimization of voltage deviation on network reconfiguration is one of the important solutions of this problem. The intelligent flow algorithm (IFA) was proposed in the past researches to solve reconfiguration issues. In this paper, the expanded flow algorithm (EFA) is proposed based on the IFA to cope with the DG installations to the distribution systems. The EFA method mainly utilizes the configuration with lower degree of supplying imbalance to search the optimal solution efficiently. The proposed EFA method is validated by simulations with 33-bus and 43-bus test distribution systems. Simulation results show that the EFA is accurate, fast and stable to solve online reconfiguration in the distribution system with DG installations.
