A high-surety microgrid-the super uninterruptable power supply-is introduced systematically in this article. Renewable energy, such as fuel cells, photovoltaic, and natural gas, are introduced in the super uninterruptable power supply to improve its reliability. First, the best architecture for the super uninterruptable power supply is selected according to the architecture performance evaluation. Second, the reliability and cost models are built to compare the super uninterruptable power supply with the traditional uninterruptable power supply. Highly reliable power distribution and power management algorithms are introduced based on the characteristics of multiple sources. Then the system stability is analyzed based on the impedance model of the super uninterruptable power supply. A highly reliable power conversion system is introduced, including redundant design and short-circuit protection. Finally, the experimental platform and experimental results are provided to verify the concept of a super uninterruptable power supply.
