Owing to the heavy fossil fuel dependence of South Korean energy-supply systems, the South Korean government has advised educational facilities, including universities, which have high electricity consumption, to use more renewable energy facilities. The present study uses the HOMER software to explore possible solutions for providing various energy resources among diesel generator, solar energy, wind energy, batteries, and the grid system to satisfy the load demand at Kyung-Hee University׳s Global Campus. The renewable fraction, cost of energy (COE), and total net present cost (NPC) of various scenarios for renewable power generation systems are calculated. The simulation results indicate that the suggested systems achieve a COE value in the range from $0.509 to $0.515 (on-grid) and from $0.525 to $0.531 (off-grid). Recommendations and limitations are discussed.
