Off-grid is the power system that is completely separated from the commercial grid, and the system is introduced in remote areas such as islands. Currently, power is mainly supplied from diesel generators, but there are some problems that operation and management costs such as fuel and transportation costs are enormous, and that CO2 emissions are very large. Therefore, off-grid systems that have installed renewable energy are attracting attention. In this paper, the power system composition of off-grid mainly based on renewable energy, operation methods that enable efficient power supply, the generator capacity determination method that enables stable power supply are proposed and economical and environmental performances, generator capacities and operational parameters are evaluated. In addition, this study uses the data acquired on the actual island and is carried out by simulation.
