Abstract :
Hybrid power system is the trend in future power systems and how to coordinate the power distribution in such a system to improve the power efficiency is the key point. In this paper, firstly a Buck-Boost DC/DC converter is discussed and voltage control is applied to maintain the output voltage stable. Then the simulation based on such a model with a DC source and a Fuel Cell(FC) equivalent electrical model is executed. Analysis of the power performance is followed. Finally, several conclusions on power distribution are obtained based on the above work.
