碩士 === 國立中央大學 === 能源工程研究所 === 105 === This study demonstrates a hybrid energy system combine with the renewable energy and hydrogen storage systems. The system is powered by wind turbines and solar cell, and a proton conducting solid oxide electrolysis cell (p-SOEC) is used for hydrogen production from excess energy. Five components install in this hybrid system: wind turbines, solar cells, p-SOEC, PEM fuel cells, and hydrogen storage tanks. The system analysis is based on the real conditions from four offshore islands of Taiwan, including of Penghu-Makung, Kinmen, Matsu, and Green Island. Effects of the system from each component are discussed and concluded. This study is analyzed by using MATLAB and Excel. The results show that enlarge the wind power percentage of Penghu-Makung would increase system energy supply. However, when the wind power percentage excess 50 %, incremental of the system energy supply becomes smaller. Solar power is stable in Kinmen and increasing the solar power penetration of Kinmen would enhance the system energy supply. In Matsu, wind power is stronger and more stable. Enlarge the wind power penetration of Matsu would increase the system energy supply. The natural condition of Green Island is similar to Penghu-Makung, but residential electricity of Green Island is smaller than Penghu-Makung. According to the natural conditions and residential electricity demand, it can be found that the hybrid system has advantages at the region with obviously periodical changes on climates. Green Island is suitable for preliminary system evaluation.
