Özet:

 

Improving distribution system reliability has received a great deal of  attention in recent years. Because of the limitation in expected budgets, it  is desirable to determine the most efficient strategy to improve system  reliability. This paper proposes a novel method to determine the optimized  operation and maintenance costs in order to decrease the failure of system  components. The proposed objective function includes the average system  frequency interruption index (ASIFI) value. To achieve the best strategy to  decrease failures of system components, it is necessary to find the minimum  value of the objective function, considering the constraints of operation  and maintenance costs. A genetic algorithm is used to solve the optimization  problem. Moreover, a new mathematical model to calculate system reliability  indices, including the ASIFI, is introduced. The proposed method is applied  to a realistic distribution system. The results illustrate the effectiveness  of the proposed method in order to increase the system reliability in an  optimal manner.
