Abstract

This study aims to analyze the techno-economic feasibility of a hybrid microgrid system designed to support commercial green tourism infrastructure on Kei Kecil Island, Southeast Maluku. The research focuses on evaluating the investment feasibility of adding a 99 kW wind power plant to an existing system comprising photovoltaic (PV), diesel generators, and batteries. The methodology employs HOMER Pro simulation to assess key financial indicators and environmental impacts, with a particular emphasis on carbon emission reduction. Simulation results indicate that the proposed hybrid scenario offers a highly profitable investment strategy, characterized by a high return on investment (ROI) and a rapid payback period of under five years. These findings confirm that integrating wind energy not only significantly increases the renewable energy fraction but also suppresses the cost of energy to a competitive level compared to conventional generation. The novelty of this study lies in the specific analysis of wind turbine intervention on a brownfield architecture in a remote island setting, distinguishing it from typical greenfield design studies. This research provides a significant contribution to policymakers and investors as a validation model for energy transition supporting sustainable tourism in archipelagic regions.

Abstract

Power quality is a crucial factor affecting the performance and reliability of distribution transformers in industrial power systems. Deviations such as harmonic distortion, load imbalance, voltage fluctuations, and transient disturbances can lead to increased losses, overheating, and reduced transformer insulation life. This study aims to analyze power quality measurements and their impact on the performance of a 1600 kVA distribution transformer using the Hioki PQ3198 Power Quality Analyzer at PT. Salim Ivomas Pratama Tbk. Real-time measurements were conducted on parameters including voltage (average 396-406 V), current (460-1060 A), frequency (50 Hz), power factor, and harmonic distortion (THD voltage <8%, THD current 6-8%) in a three-phase system with ABB Dyn5 specifications, ONAN cooling, and 5.9% impedance. A quantitative descriptive method with field data analysis revealed stable voltage and frequency with no significant voltage dips/swells, and voltage harmonics complying with IEEE 519 standards, although current harmonics were relatively high due to non-linear loads like inverters. The evaluation results indicate relatively good power quality, with optimal operational efficiency and low risk to equipment degradation, supported by normal transformer oil DGA analysis (TDCG 197 ppm). However, elevated current THD poses potential efficiency losses and accelerated aging, recommending harmonic filters, periodic monitoring, and load balancing to enhance distribution system reliability. This research provides insights into the relationship between power quality and transformer performance, supporting preventive maintenance in industrial installations.
