Abstract
South Korea’s main industry is the manufacturing industry, and it requires stable energy. Korea heavily relies on importing oils to produce energy, thus efficient energy management is critical. This is why many renewable and smart energy policies and infrastructure planning are being set up currently. Supplying reliable and sustainable renewable energy to remote areas has especially been questioned; therefore, adopting sustainable and clean energy based on renewable resources cannot be delayed any more. This research examines the most economically, technologically and environmentally suitable energy grid of two South Korean Islands. Several hybrid energy system configurations that analyze and identify the optimal grid-connected and grid-independent hybrid power generation systems are simulated in this study. According to the results of the study, the optimal regionally detached power generation system was the wind-PV-battery-converter hybrid system. At the end of this paper, implications and limitations are discussed.
Highlights
In current supply dominated paradigms, the efficient management of central grids, which work as a backbone system, has emerged as a crucial issue while demand management has gradually gained momentum [1]

Numerous global industrial complexes and university campuses have adopted the micro-grid for their sustainable development as they have recognized the importance of an independent power system with a stable renewable energy supply [10,11,12,13]
Summary
In current supply dominated paradigms, the efficient management of central grids, which work as a backbone system, has emerged as a crucial issue while demand management has gradually gained momentum [1] This is why the economic feasibility analysis of on-/off-grids is needed to connect micro-grids with the central grid in a more effective way for increasing energy independency [2,3,4]. The Korean government has understandably high motivation for seeking sustainable and efficient plans for renewable energy since Korea has limited natural energy resources [1,16,17].
