Abstract

This paper presents a new computational procedure for obtaining the optimum feeder grading solution. The procedure is extremely simple and does not involve the use of dynamic programmin. This is a major achievement as it eliminates (i) the bulk of computation, (ii) the need for large computation storage, (iii) the need for complex computer programming. The proposed procedure is so simple that all the required calculations can be done on a small programmable calculater specially in case of single radial feeder without laterals. Also, the procedure enables to handle the variations in the load growth rate, load factor, cost of energy, etc. Over the planning period. The presented optimization problem minimizes the sum of feeder cost and the present worth of the feeder energy costs, while keeping the voltage regulation within a prescribed value.
