Abstract
While environmental and energy concerns have become global issues, the government of South Korea has made notable efforts and formulated plans for the diffusion of renewable energy generation facilities for the nation’s public and governmental institutions. Accordingly, Jeju Island has become one of the most promising locations for utilizing renewable energy resources. This study aims to propose potential configurations for renewable energy generation facilities (mainly solar and wind energy facilities) in response to the electricity demand of the main local governmental offices of Jeju Special Self-Governing Province. The study utilizes the hybrid optimization of multiple energy resources software to simulate two optimized configurations for generation at a cost of energy of $0.306 per kWh (independent) and $0.204 per kWh (grid-connected) with 100% renewable fraction for the island. The implications of the simulation results and limitations of the study are discussed.
Highlights
The Act on The Promotion of the Development, Use and Diffusion of New and Renewable Energy was revised in 2013 and, since it has played a primary role in supporting the renewable energy industry by obligating newly established buildings with a total floor area of more than 3000 m2 to invest at least 5% of the entire construction cost in a renewable energy system [1]
The Act has been strictly executed, especially with regard to national and local government institutions and offices. Under this Act, the South Korean government initiated the Renewable Energy Portfolio Standard (RPS) and Feed-in-Tariff (FIT) programs, which require electricity suppliers to provide a minimum ratio of their electricity demand via appropriate renewable energy resources [2]
The South Korean government has stipulated that both public and private sectors should actively participate in the distribution of renewable energy generation facilities and focus on meeting the citizens’ electricity demands [3]
Summary
The Act on The Promotion of the Development, Use and Diffusion of New and Renewable Energy was revised in 2013 and, since it has played a primary role in supporting the renewable energy industry by obligating newly established buildings with a total floor area of more than 3000 m2 to invest at least 5% of the entire construction cost in a renewable energy system [1]. Jeju continues to implement its carbon-free policies and proposes to achieve more than a 50% renewable fraction, establish smart-grid systems, and utilize wind turbines to generate more than 2 GW of electricity (capacity-oriented) for the island [9] Both the national and local governments plan to disseminate renewable energy infrastructure throughout Jeju so as to supply approximately 330 MW and 850 MW by 2020 and 2030, respectively [10].
