  • Under the goal of analyzing the compulsory supply share of new renewable energy according to the application of a daylighting system to indoor gymnasiums, this study conducted analysis of energy consumption and operation schedule at three indoor gymnasiums in the nation through a survey. The investigator did an Energy Plus simulation on Building A based on the analysis results and analyzed the supply share of new renewable energy in the saving effects of lighting energy according to the application of a daylighting system. As a result, When 92 prism daylighting system were installed in the upper ceiling of a stadium, they were able to meet the criteria for the minimum illumination for official games(Min : 600㏓) and optimum illumination for general games and recreations, thus saving lighting energy during the daytime(09:00~17:00). The resulting saving effects of lighting energy amounted to 44.4% for official games, 57.6% for general games, and 66.7% for recreations. In addition, the daylighting systems had a compulsory supply share of new renewable energy at 2.04% for official games, 2.75% for general games, and 2.62% for recreations, recording an average compulsory supply share of 2.5%.

  • The reliable Typical Meteorological Year (TMY) data, sometimes called Test Reference Year (TRY) data, are necessary in the feasibility study of renewable energy installation as well as zero energy building. In Korea, there are available TMY data; TMY from Korea Institute of Energy Research (KIER), TRY from the Korean Solar Energy Society (KSES) and TRY from Passive House Institute Korea (PHIKO). This study aims at examining their characteristics by using Principle Component Analysis (PCA) at six ground observing stations. First step is to investigate the annual averages of meteorological elements from TMY data and their standard deviations. Then, PCA is done to find which principle components are derived from different TMY data. Temperature and solar irradiance are determined as the main principle component of TMY data produced by KIER and KSES at all stations whereas TRY data from PHIKO does not show similar result from those by KIER and KSES.

  • New & renewable energy technology development has been carrying out in 11 different areas so far. Many technologies are being applied to the required areas according to its own characteristics. Before launching the development, these technologies have been evaluated by their commercial effect and contribution to energy supply. In this paper, the impact factors enhancing the distribution of renewable energy were developed to select appropriate diffusion regulations for each technology area. In addition, AHP methodology was introduced to investigate priorities of the regulations along with weights of impact factors.

  • New and renewable energy has attracted a significant attention since the Paris Agreement in 2015. Especially hydrogen energy is important for reducing greenhouse gas produced during transportation. The new government suggested that the eco-friendly vehicles, hydrogen infrastructure and the development of new and renewable energy are the major growth engines in the future. Hydrogen energy is also concerned as the main part of our economy in the national affairs. In the policy of Mission Innovation Strategy and the third Eco-Friendly Vehicle Master Plan, government presents the status, future direction, technical road map and distribution road map of hydrogen energy. With this trend, investments in the research and development on hydrogen and fuel cells have expanded and will continue to expand for the implementation of the policy. The cost reduction, technical innovation and the increase in the localization rate are required for the new and renewable energy, including hydrogen energy, to become the future growth engine.

  • Recently, an UAV using green energy for propulsion has been developed due to exhaustion of fossil fuel. This aircraft runs on electric motors rather than internal combustion engines, with electricity coming from fuel cells, solar cells, ultracapacitors, and/or batteries. Especially solar cells are installed in HALE UAV and flight tests are performed in the stratosphere. Although the solar powered UAV has the advantage of zero emission, its energy conversion efficiency is low and operation time is limited. Therefore, the solar powered UAV has been designed to operate with the secondary battery obtaining flexibility of energy management. In this study, we suggest the new operational concept of the solar powered UAV using directed-energy rayed from the surface of earth to UAV. An UAV is able to secure additional power through attaching solar cell to the lower surface of elevator. As a result, the additional energy supplied by directed-energy can improve the energy management and operational flexibility of the solar powered UAV.

  • This study compared and analyzed major policies and operational processes of countries that introduced the Renewable Energy Plan Site, through literature analysis of published governmet data, and previous research results. The procedures of the Renewable Energy Plan Site were classified into planned location designations, selection of power generation business operators, designation of the business' district and development and evaluating the factors derived for each procedure. Four contries were selected to be compared and analyzed, namely: Denmark, Germany, the United Kingdom and Japan. This was based on the criteria used to introduce and operate the Renewable Energy Plan Site, activate renewable energy supply and check the applicability of Korea's policies. It was analyzed that the priority of the planned location for the procedure was different for each country depending on the conditions there.
