OPTIMALISASI DESAIN PEMBANGKIT HYBRID DI PULAU BANGKURUNG MENGGUNAKAN ANALISIS MULTI KRITERIA

Abstract

Bangkurung Island is a remote area in Southeast Sulawesi that is electrified for 8 hours per day by a diesel
generator with a supply capacity of 850 kW and a peak load of 466 kW. This study aims to analyze
electricity generation by utilizing local renewable energy-based hybrid plants that can meet demand for 24
hours per day. For this reason, 5 alternative Planning design schemes are proposed: first 100% PLTD
composition, second PLTD+PV+Li-ION, third PLTD+WT+Li-ION, fourth PLTD+PV+WT+Li-ION, and
fifth PV+WT+Li-ION. Based on the simulation results of the HOMER application for the five schemes
above, multi criteria decision making is carried out to determine the best alternative scheme based on
several criteria using the TOPSIS (Technique of Preference by Similarity to Ideal Solution) method, the
results obtained in the fourth scheme with the highest value and has a Cost of energy (COE) value of US $
0.105 / kWh. Although the results of the financial feasibility analysis study which includes Net Present
Value (NPV), Profitability Index (PI), and Internal Rate of Return (IRR) are not feasible. Based on the
economic analysis of the best hybrid scheme, the usual fuel savings of US$ 597,239.21 / year and the
environmental aspects of reducing CO2 emissions by 1.99 tons / year and reducing waste treatment efforts
from diesel power plants.
