These main goals of the restoration in distribution networks are to reenergise loads in the area where the power outage occurs. In this study, a new multi‐stage restoration process by the aid of the decision‐making tree algorithm is proposed to maximise the restored loads and also to minimise switching operations in the distribution networks with distributed generations (DGs). This method includes three stages of initial restoration, reconfiguration and optimal load shedding. In order to reduce the search space, the network switches are categorised into different sets which avoid moving to any inappropriate result space. The simulations are carried out on the 69‐bus distribution system and the results show the high capability and accuracy of the proposed method in the restoration of distribution networks.
