Distribution systems, Economics, Cost, Hierarchy


An electrical power distribution cost model is developed for a power distribution system based on power and energy flow. The model allows for the study of multiple energy classes, such as primary and secondary energy. Embedded costs are used for individual units including feeders, trans formers, lines in addition to overhead cost, cost of losses etc. The model is recursive and hierarchical and is ap plicable to different voltage levels, spatial distribution of equipment, varying load, utilization and coincidence fac tors and will be applicable in determining distribution tar iffs and real costs under various conditions in the system.
