Feeder reconfiguration is commonly used in the distribution system for real loss minimisation. However, in the stressed system condition, loadability limit enhancement is an important issue. This aspect has not been paid much attention in the literature. Metaheuristic methods can solve this problem at a high computational cost. In this view, an efficient two‐stage algorithm is proposed for the same. In the first stage, an efficient reactive power loss minimisation‐based reconfiguration plan is obtained. Using heuristics from this solution, the second‐stage employees improved harmony search algorithm for reconfiguration with loadability enhancement. It is important to note that this algorithm is used only when system load is near the critical load; otherwise, the conventional real power loss minimisation reconfiguration plans can be used. Results for a 33‐bus balanced test system and a 25‐bus unbalanced distribution system confirm the potential of the proposed method.
