چکیده
This paper presents a closed-loop control of an 800W fuel cell power system consisting of phosphoric acid fuel cell (PAFC), an ultracapacitor, power controlling unit and grid side filters. Simulation results represent the dynamics of the PAFC and its related power conditioning devices including grid connection. The proposed model is based on mathematical equations. The modeling and simulation is done in MATLAB/Simulink environment. This model mathematically computes cell output voltages and losses. The model includes dc power conversion of fuel cell output into ac and grid interface. Proposed model is lucid and simple. Keywords— Phosphoric Acid Fuel Cell; Ultra-Capacitor; Modeling and Simulation; Power Conditioning unit; LCL Filters; Distributed Generation

In this paper, a supervisory controller is proposed to manage the power flow in a hybrid AC/DC micro-grid for both grid-connected and disconnected modes. When the hybrid AC/DC micro-grid is connected to the utility grid, power surplus or shortage leads to power trade between the micro-grid and the utility grid. In the grid-disconnected mode, the renewable power sources (wind and solar generatio...
