Distribution system reconfiguration has become a useful and affordable method for both real time and planning stages. Protection system is an inseparable part of the power systems, hence it should not be neglected in the process of feeder reconfiguration. This study introduces an executable reconfiguration method in real distribution networks considering operation and coordination of protective devices of the network. The objective of this study is to attain a configuration of the network, which achieves minimum active power loss and voltage deviation while protection system functions properly. In this regard, precise constraints are introduced and formulated to exclude configurations of the network, which may cause mis‐coordination in protection system performance. Necessity and effectiveness of the constraints are demonstrated on 33‐bus, 69‐bus and 119‐bus distribution test systems.
