Economic and Environmental Assessment of Wind Turbines for Hybrid Power Systems in Bawean Island

Abstract

The design of wind turbines for a hybrid power system in Bawean Island is explored in this study. Bawean Island faces significant challenges in electricity access, with approximately 8,000 families lacking power. The primary load demand is 2.8 MWh/day with a peak load of 454 kW. Using the Hybrid Optimization Model for Electric Renewables (HOMER), several wind turbine models were assessed, including BWC Excel R, Synergy S3000, Synergy S20000, Synergy S5000DD, Jacobs 29-20, Fuhrlander 250, and Fuhrlander 30. The analysis compares these turbines based on their total Net Present Cost (NPC), Cost of Energy (COE), excess electricity generated, and renewable energy fraction. The results show that wind turbines with AC generators perform better in terms of cost-effectiveness and environmental impact, with the Fuhrlander 250 model being the most optimal, offering the lowest NPC and COE, along with a high renewable fraction. This study contributes to optimizing hybrid power systems in remote island regions, enhancing the sustainability and reliability of energy generation.
