Optimal sparing for SF6 gas insulated substations
A method is suggested to optimize the number of spare items of substation components which have to be stored at the beginning of each year throughout a planning period. This sparing policy is conceived to provide the minimum total cost consisting of investment and load curtailment costs. The method uses the Hooke and Jeeves' direct search optimization approach. The optimization method is extended to apply to typical HV/MV GIS transformer stations requiring specific reliability modeling.
