Optimasi Pemilihan Lokasi Prioritas Pemasangan LBS Menggunakan Metode FUZZY AHP-TOPSIS (Studi Kasus: PT. PLN UP2D Sumatera Utara)

Abstract

PT PLN Unit Pelaksana Pengatur Distribusi (UP2D) is responsible for maintaining the reliability and efficiency of electricity distribution. UP2D has set success indicators such as Energy Not Served (ENS), System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI) as measures to improve reliability. One of the approaches taken is the installation of Load Break Switches (LBS) as outlined in the 2023 Rencana Kerja Anggaran Perusahaan (RKAP), which assigns PT PLN UP2D to install 250 new LBS units on feeders. However, UP2D does not have a clear method for determining the distribution and priority of LBS installation among feeders. Therefore, this research utilizes the Fuzzy AHP and TOPSIS methods as optimization tools in decision making to determine the priority of feeders. The objective of this research is to determine the ranking of feeder priorities using performance scores as a reference. In this study, 253 feeder alternatives were analyzed using six criteria: ENS, SAIDI, SAIFI, feeder load, feeder length, and internet signal condition. The weighting results show that the highest weight is assigned to the ENS criterion, amounting to 35.6%. Based on the ranking through performance scores, 67 priority feeders were selected for the installation of 100 new LBS units.
