Multi-objective Modeling for Fault Indicators Placement Using of Nsga Ii to Reduce off Time and Costs in Distribution Network

According to the reports of power companies, about 80-90% of the outages occurred in the network are due to the error in the distribution system. The occurrence of these outages leads to the customer dissatisfaction and the lack of energy sales and significant economic losses in the distribution companies. Thus increasing network reliability to reduce these losses has attracted the attention of many experts. In this paper, fault indicator placement is performed using multi-objective function. Creating high reliability and reducing costs are the main goals of this paper and for this purpose multi-goal objective function is used. Fault indicator placement caused a plan with respect to all conditions governing the issue. Optimization of this problem, especially for large networks is a complex and difficult task. In this paper, NSGA II algorithm is used for optimization.
