Resumen de Optimal reliability design in an electrical distribution system via a polynomial-time algorithm
In this paper, the optimal design of reliability indices in an electrical distribution system and their impact to planning are studied. By formulating the cost due to interrupted KVA-hour, initial interruption cost, and modification cost in terms of component reliability indices, an optimization problem is derived while simultaneously considering multiple load points and feeder capacity limits, resulting in a nonlinear programming problem. To solve this nonlinear programming problem, an effective polynomial-time algorithm is presented. The numerical test shows that not only significant savings can be achieved, but also information on identifying value-saving feeder/components can be revealed as well. This is a valuable tool to distribution planning/operations.
