This paper presents a fuel-cell distributed energy resource with integrated energy storage. A compatible power electronic interface to couple the fuel-cell with the grid and/or a local load is introduced. Details of the energy storage module, the power electronic interface and the corresponding controls are described. A control strategy for the power electronic interface is developed to manage the flow of power between the fuel-cell, the energy storage and the grid. A dynamic model for the fuel-cell distributed resource is developed and is used for the systematic design of the distributed resource control system. Performance of the fuel-cell distributed energy resource is evaluated based on digital time-domain simulations in the (Electromagnetic Transient Program) EMTP-RV software environment. Effectiveness of the energy storage module, the compatible interface and the corresponding controls in enhancing the fuel-cell distributed resource performance is verified. The results demonstrate the developed power electronic interface and control strategy provide the fuel-cell with the load-following capability, the plug-and-play feature and high qualities of voltage and power that are required for the microgrid application.
