Robustness Comparison of TOPSIS, VIKOR, and PROMETHEE II for Prioritizing Switching Device Placement in Power Distribution Networks

This paper continues previous research on the prioritization of switching device placement in power distribution networks. The aim of this study is to evaluate the robustness of three different multi-criteria decision-making approaches. The criteria considered include Energy Not Served (ENS), feeder length, network availability, System Average Interruption Duration Index (SAIDI), and System Average Interruption Frequency Index (SAIFI). Through conducting a sensitivity analysis on the weightings of the criteria, the robustness of each method is assessed. Robustness is measured using standard deviation, range, and Spearman correlation. The results demonstrate that PROMETHEE II is the most robust method. From 30 feeder alternatives, the top 10 feeders are identified, with ULP Kanopan receiving the highest allocation of LBS units, totaling three units, consistent with previous findings.
