Time varying load analysis to reduce distribution losses through reconfiguration

Economic Analysis of Power Transmission Lines using Interval Mathematics

“…Modelling and optimization of power flows in electric power transmission and distribution networks using interval analysis was described by earlier researchers [15][16][17][18][19]. Application of uncertainty analysis for various applications in distribution systems such as compensation studies, feeder sizing and loss reduction were discussed in the literature [20][21][22][23]. Reliability analysis of transmission and distribution systems to evaluate uncertainty using interval mathematics was presented by earlier researchers [24][25].…”

Sensitivity and functionally oriented models for power system planning, operation, and control

“…It permits one to solve the problems as on-line, real time problems. Many works have been dedicated to their solution in a monocriteria as well as multicriteria statements on the basis of diverse approaches (for example, [2,[19][20][21][22][23][24][25][26][27][28][29][30]). These works ''compete'' in aspiration for obtaining ''more optimal'' solutions.…”

“…However, this aspiration, considering that the combination of the information uncertainty and relative stability of optimal solutions produces decision uncertainty regions [19,31], is not convincing. At the same time, the results of [2,[19][20][21][22][23][24][25][26][27][28][29][30] as well as other works in this field do not permit one to consider a power system reaction when optimizing distribution system configuration.…”

Load type impact on distribution system reconfiguration

“…The approach presented by Broadwater et al [11] calculates the switching patterns as function of time which may be performed on seasonal or daily basis. The voltage dependency has been considered at the circuit level and it has been shown that the configuration at system peak can reduce losses but may cause a marginal increase in system peak intakes.…”
