Abstract :
In this paper, a performance analysis of a dc-bus voltage control for hybrid parallel-connected sustainable energy conversion system is presented. The hybrid system is the combination of fuel cell (FC), wind turbine, and battery storage via a common dc-bus. These hybrid sources are interfaced to dc-bus through high frequency-based power converters. The main advantages of the proposed topologies are: simplicity, robustness, and high efficiency due to high frequency converter operation as well as reduced number of elements. The complete operation for each converter and theoretical analysis are presented. The concept of the hybrid system and its control is described. Experimental results are presented and discussed.
