  4. Abstract:
  5. Distribution networks are designed in loop structure, while they are operated as radial networks. In this regard, the location of normally open (NO) switches is usually determined by either minimizing real power losses or maximizing the reliability level. However, considering both losses and reliability in the decision making procedure may lead to a better solution. To do so, this paper proposes a mathematical model to find the optimal configuration of NO switches such that losses and reliability are optimized. The multi-objective model is scrutinized via weighted sum approach to achieve a single-objective model. The model is formulated in mixed integer quadratically constrained programming (MIQCP) format which can be easily solved in an effective run time. The effectiveness of the model is revealed through various scenarios and sensitivity analyses by simulating a real Finnish distribution network. © 2017 IEEE
