دانلود Simultaneous distribution system reconfiguration and DG sizing algorithm without load flow solution

Abstract

This  study  presents  a  loss  formula-based  simultaneous  reconfiguration  and  distributed  generation  (DG)  sizing algorithm for active power loss minimisation in distribution networks. A new heuristic technique based on the exact loss formula for  reconfiguration  is  proposed.  The  exact  loss  formula-based  analytical  approach  is  used  for  DG  sizing  and  siting.  The proposed  algorithm  is  tested  on  33-,  69-,  84-  and  136-bus  distribution  systems.  The  simulation  results  demonstrate  the effectiveness of the proposed approach to obtain the best solution. The impact of the initial voltage selection on this approach is analysed. The results are suggesting that it requires no load flow solution and it is the unique feature of this approach. The proposed approach can be used as a primary analysis tool for active distribution network real-time operation and planning. The proposed method further extended to the multi-objective approach using the weighted sum technique.
