This paper explores the techno-economic feasibility of renewable power generation in a remote South China Sea island, seeking to substitute the existing diesel generator with a PV-wind-diesel-battery hybrid energy system (HES). First, the authors assessed the availability of local renewable energy resources, elaborated the dispatch strategy of the HES, and introduced the load curve, system configuration, techno-economic specifications of the major components. Then, the Hybrid Optimization of Multiple Energy Resources (HOMER) software was employed to simulate and optimize the HES. In order to identify the optimal configuration of the system, different combinations of the HES were simulated before comparing the economic and operation information of the feasible alternatives. Through the simulation and optimization, it is concluded that the HES can provide sufficient and reliable power to the study area. Finally, the economic and resources sensitivity analysis was performed to identify how the optimal design is to change with the sensitivity variables.
