Abstracts The tourist sectors in South China Sea, Malaysia (SCSM) completely depend on diesel generators for 24h power supply. The emissions from diesel based power plants are environmentally risky for tourist spots. In this research article, a multi-optimal combination of stand-alone hybrid renewable energy system (HRES) for a large resort center located in SCSM has been proposed with detailed operational performance analysis. Hybrid Optimization Model for Electric Renewable (HOMER) software is used for economic and technical analysis of the system. The estimated peak and average load per day for the resort are 1185kW and 13,048kW respectively. The best optimized stand-alone hybrid energy system comprises of PV, wind, diesel generator, converter and battery. The optimized system resulted in net present cost (NPC) of $17.15 million, cost of energy (COE) of $0.279/kWh, renewable fraction (RF) of 41.6%, and CO2 of 2,571,131kg/year. Whereas, the diesel only system takes NPC of $21.09 million, COE of $0.343/kWh and CO2 of 5,432,244kg/year. The diesel only system has higher NPC, COE and CO2 emission than optimized HRES. The designed and analyzed HRES model might be applicable to any tourist locations and decentralized places in SCSM and around the world having similar climate conditions.
