Decision theory criteria for medium voltage cable sizing in presence of nonlinear loads

In designing a distribution system, engineers have to choose optimal soluti ons under environmental uncertainty; in most cases, among the uncertainties the ones deriving from the presence of nonlinear loads must be included. U nder these conditions, the Decision Theory appears to be a valuable tool fo r solving distribution design problems. This paper considers three approach es based on the Decision Theory for the economical sizing of medium voltage distribution electrical lines under uncertainty, paying particular attenti on to harmonics due to nonlinear load presence. In the last part of the pap er the implementation and practical application of the sizing procedures ar e discussed and compared in some case studies. (C) 2001 Elsevier Science Lt d.
