Optimal conductor selection in planning radial distribution systems

Optimal secondary distribution system design considering plug-in electric vehicles

“…The top-oil temperature rise at a time after a step load change is given by the exponential expression given in (7); first, the percentage of initial and ultimate load to the rated load (K i and K u ) is calculate, with the knowledge of the transformer oil time constant ( TO ), the type of cooling system, the change of top-oil temperature rise can be found at each load level by calculation of the load increase percentage. The transient winding hottest-spot temperature rise over top-oil temperature is given in (8), this depend on the winding time constant ( W ) and the initial and ultimate load percentage.…”

“…Studies [7][8][9] focused on distribution system design based on the selection of the optimal conductor sizing to minimize overall cost and system losses, the authors ignored distribution transformers in SDS design. On the other hand, studies [10,11] were applied only to three-phase distribution system.…”

Design of large rural low-voltage networks using dynamic programming optimization

“…It is considered that the tree is fed by only one mv/lv substation, and when this is not possible the cost value is infinite. The proposed algorithm considers mv/lv substation location as not fixed, so is an improvement of Tram and Wall's [7] method where mv/lv substation locations are considered fixed.…”

“…Snelson and Carson [6] proposed solving the conductor optimization problem using continuously tapered distributor criteria and a variable cable cost/voltage drop function. Tram and Wall [7] present a process based on dynamic programming to solve the conductor optimization problem.…”

Optimal conductor selection for radial distribution systems

“…The researchers proposed an objective function for optimizing the conductor cross section. Tram and Wall [6] worked on similar grounds where again the authors took different examples of feeder systems and calculated the best conductor for each feeder segment based on specific requirements of voltage and losses.…”
