Techno-economic optimization and sensitivity analysis of a hybrid renewable microgrid for local market electrification in developing countries.

This project studies how to design and evaluate a hybrid renewable microgrid that can power local markets in developing countries, looking at both technical performance and cost. Rural and semi‑urban commercial areas often face unreliable grids and expensive power. To address this, the study examines combining several distributed energy sources—solar photovoltaic panels, wind turbines, battery storage, and a backup diesel generator. Detailed mathematical models and simulations are used to calculate key metrics: – Levelized Cost of Energy (LCOE) – Net Present Cost (NPC) – Greenhouse‑gas emissions A thorough sensitivity analysis checks how changes in the following factors affect the system’s feasibility: – Fuel price fluctuations – Variations in solar irradiance

– Uncertainty in future load growth – Capital costs of components The methodology gives clear steps for creating resilient, affordable, and sustainable energy solutions that match the specific demand patterns of local markets. It also provides practical tools and analytical frameworks for microgrid planning, helping engineers size systems and choose operating strategies while dealing with changing economic and environmental conditions.
