Abstract
Remote mangrove ecotourism sites, constrained by environmental sensitivity and limited grid access, rely on costly, polluting diesel generators. This study designs and validates hybrid renewable energy systems for sustainable tourism in the Sundarbans (Bangladesh), Can Gio (Vietnam), and Guaratiba (Brazil). Using HOMER Pro, system sizing and long-term costs are optimised on the basis of local solar, wind and biomass resources and multi-sector electricity demand, while DIgSILENT PowerFactory is used to verify steady-state and dynamic performance through load-flow and fault analyses. The optimised hybrid systems achieve 80–85% renewable penetration, with the Sundarbans leading due to strong wind and biomass resources, and reduce total energy costs by 22–35% and greenhouse gas emissions by more than 70% compared to diesel-only supply. Across the three sites, the levelized cost of energy falls in the range of approximately 0.11–0.21 USD/kWh, versus more than 0.30 USD/kWh for existing diesel-based generation, while the contribution of diesel generation is greatly reduced, consistent with the large decrease in associated emissions. Voltage deviations remain within ±5% of nominal levels, line loadings stay below thermal limits and fault recovery under 2 seconds, indicating that the proposed configurations can provide reliable and resilient power under disturbed operating conditions. Overall, the integrated HOMER–DIgSILENT framework offers a scalable model for planning low-carbon electrification of ecologically sensitive mangrove regions, supporting progress towards Sustainable Development Goals 7 (affordable and clean energy), 8 (decent work and economic growth), 9 (industry, innovation and infrastructure), 13 (climate action) and 15 (life on land), while enhancing local energy security and sustainability.
