dc.description.abstractThis paper presents the design, simulation, and performance evaluation of a grid-connected hybrid renewable energy microgrid system for Ajayi Crowther University in Oyo, Nigeria. The system integrates wind turbines, solar photovoltaic panels, battery energy storage, and grid connection to address persistent challenges of unreliable national grid supply, high diesel generator costs, and environmental pollution. Using MATLAB/Simulink, HOMER Pro, and PSCAD simulation platforms, a comprehensive techno-economic analysis was conducted based on one year of meteorological data (April 2024 - April 2025) and detailed load profiling of the Engineering Faculty and Diocese of Lagos West (DLW) Female Hostel. The optimised system comprises 300 kW wind capacity (three 100 kW turbines), 250 kW solar PV, 600 kWh battery storage, and 700 kW inverter capacity. Simulation results demonstrate that the hybrid system achieves a 74.3% renewable energy fraction, generating 817,820 kWh annually from renewable sources while reducing grid dependency to 25.7%. The system delivers annual CO emission reductions of 436.7 tonnes and demonstrates economic viability with a levelised cost of energy of $0.198/kWh and a payback period of 12.3 years. This study contributes to the growing body of knowledge on hybrid microgrid applications in Sub-Saharan African university campuses and provides a replicable framework for similar institutional electrification projects in developing regions
