Distribution Network Reconfiguration in a Multi-objective Optimization Framework Using Runner and Root Algorithm

In this paper, distribution network reconfiguration problem has been modeled and solved. This problem is related to power system operation studies from the time point of view. Network losses, voltage profile, risk of lines loading, and system reliability are indices that have been considered in the operation phase. The network losses have been calculated by power flow tools. Also, uncertainties in demand and topology of radial distribution network have been included in the problem formulation. In this paper, uncertainty in demand has been modeled using fuzzy formulation of load level and fuzzy power flow by triangular numbers. The proposed framework has been modeled as a multi-objective problem and solved using runner and root algorithm (RRA). Technical limitations beside assumption of radial network considerably reduce the search space of the algorithm. The proposed model has been tested on IEEE 33-bus distribution system. The simulation results show the effectiveness and robustness of the proposed solution method.
