| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 95 === As the petrochemical resources are running short gradually, most modernized countries started to explore renewable energies. As a kind of enormous substitutive resources, the solar energy is considered as one of the best solutions to meet energy crisis in the future.
In this thesis, one focused on two subjects: the first is the assessment and design of the grid-tied photovoltaic system, including the analysis of the system configuration, environmental factors, the capacity of installation, the selective analysis of the relevant equipments and the procedure and requirement for connection with Taipower electric system such as preparing necessary documents, what should to be taken care for operating and the selling-back regulation of Taipower electricity.
The other keypoint is that, for the sake of preventing the isolated island effect, the photovoltaic system will stop working immediately when the power outage occurred, an available solution was proposed by utilizing emergency diesel generator to re-operate the grid-tied photovoltaic system. With the system operating limits, one examines results according to different power demand and adjusts the optimal source dispatch. In addition, the main stadium of the 2009 Kaohsiung world games also designed with the grid-tied photovoltaic system, it is the best case study hereby at the same time. The study results will be helpful to the design of the grid-tied photovoltaic system.
