This paper proposes a resource evaluation and validation study of a grid-connected hybrid power system which tends to maximize the use of renewable energy generation with energy storage systems while minimizing the total system cost. The HOMER (Hybrid Optimization of Multiple Energy Resources) Grid software is adopted in this study to find the optimal configuration of solar energy sources with battery storage systems to deliver complementary electricity supply to satisfy AC primary load of 68.55 kWh/day with a 10.2 kW peak load demand to a building on a University campus premises located in the Niger Delta region of Nigeria. The results obtained from simulations showed a list of feasible resource configurations for the hybrid system. However, the most optimal/economical configuration is a grid-connected Solar PV-Gasoline system with a least cost of energy (COE) at ₦93.83/kWh and 6.7% renewable energy fraction.
Key words: Electricity, DG, HOMER Grid Software, Renewable Energy, Optimization, Solar PV
