In the PEMFC system, the oscillogram of the current is stable while the current is 1A; however, when the current is changed into 2.1A (subject to the power is 230W), the current output fluctuates and twists. After comparing the result generated from the simulation test of PSIM and experiment with the real data, this theory of the dissertation is proved to be workable.

本论文之研制之质子交换膜燃料电池电能转换系统，当电流为1A与1.9A时，电流波形图相当稳定，而当电流改变成2.1A时，此时功率约为230W，其输出电流波形及产生扭曲变形较不稳定，经由PSIM软体模拟与实验比较得出稳定燃料电池发电系统，并且与实际量测结果互相比较，以验证本文研究系统之可行性。

For the current situations that electrical power operation environment is more complex, the power organization reformconstantly, the electricity market is formed step by step, the current electrical equipment is outdate, and for the so many problems that lowenergy efficiency, poor power quality, less interaction between customers and power grid company, this paper defines the smart grid that is suited to China's power grid situation, and summarizes five features for the smart grid such as self-healing, interactive, optimization,compatibility, integration and the differences between smart grid and traditional grid, then introduces the four systems of smart grid and two foundations before building the smart grid, and finally concludes that smart grid is the inevitable result for the economical and technological development.
