*2.3. Energy Supply Security Analysis: Korea Case Study*

Several research works on the evaluation of the energy supply security of Korea have also been conducted during the past decade. Their purpose is to understand the position and characteristics of energy supply security in Korea and to suggest energy policy prescriptions. Due to insufficient natural resources alongside economic and geopolitical uncertainty, the accessibility and availability of energy have been concerns for Korea. The top priority in energy supply security has thus been to avoid any disruption of the energy supply [9]. Jun et al. [23] presented the energy security costs for energy sources contained within the Korean electricity market. The minimum cost of ensuring energy supply security was measured as a supply disruption in the case of electricity generation and an energy portfolio with the lowest cost is suggested. Ryu et al. [31] investigated three scenarios with different levels of carbon emission, energy security, and electricity generation costs in Korea. Through these scenarios, the appropriate portions of specific

energy resources for electricity generation were given for executing national energy policy strategies. Ahn et al. [32] also suggested the optimal allocation of energy resources for electricity generation by scenario-based analysis for sustainable development and lessened external risks to energy security in Korea. These studies have mostly concentrated on the energy mix for electricity as a form of final energy. Although there have been many attempts to analyze secure electricity generation in the country, there is a lack of research that investigates the primary energy supply. As energy resources have recently become more diverse than ever before with the development of energy conversion technologies and applications, this study includes various resources, including fossil fuels, nuclear, and renewable energy.
