The increasing global demand for clean, reliable, and economically viable electricity has accelerated the adoption of micro-grid systems integrating multiple renewable energy technologies. Hybrid renewable micro-grids combining resources such as solar PV, wind, biomass, and energy storage offer significant potential for enhancing energy resilience while reducing dependence on fossil fuels. However, determining the optimal configuration of these systems requires comprehensive evaluation of their technical performance, economic feasibility, and long-term sustainability. This study presents a techno-economic sustainability analysis of optimal micro-grid systems incorporating hybrid renewable energy technologies. Using advanced optimization techniques, the research assesses system configurations under varying load demands and resource conditions to achieve an optimal balance between cost, reliability, and environmental performance. Key indicators such as Levelized Cost of Energy (LCOE), Net Present Cost (NPC), renewable fraction, system reliability index, and carbon emission reduction potential are analyzed to quantify the system's performance. The findings demonstrate that properly optimized hybrid renewable micro-grids can significantly reduce lifecycle costs and emissions while ensuring a stable power supply, making them a viable solution for rural electrification, grid support, and sustainable energy transitions. This work provides critical insights for policymakers, system designers, and energy planners seeking to implement resilient, low-carbon micro-grid systems for enhanced energy sustainability.
