本研究旨在解决利用可再生能源建设智能电网的问题。首先，构建了燃料电池仿真器的制作方法，降低了系统的开发成本。其次，针对智能电网对电能波动的补偿特性，提出了改进飞轮储能系统性能的方法。第三，提出了用双电层电容器分析电力补偿系统的方法，并对控制参数的设计有了一定的了解。最后，给出了电池功率补偿系统中补偿性能与电池容量的关系，得出了系统搭建时的容量分析结果。

This study is to solve the problems to construct the smart-grid system by using renewable energy. First, we constructed the method to make fuel cell emulator to reduce the system development cost. Second, we proposed the method for improving the performance of fly-wheel energy storage system to improve the characteristics of compensating fluctuating power in smart-grid. Third, we proposed the method to analyze power compensating system using EDLC (Electric double-layer capacitor) and got a certain knowledge on how to design the control parameter. Finally, showing relationship between compensation performance and battery capacity in battery power compensating system, obtained the findings on capacity when building a system.
