Grid Tied Solid Oxide Fuel Cell Power Generation System for Peak Load Management

Solid Oxide Fuel Cell (SOFC) based Transportation system have been reported as the future of human society. The SOFC based systems are pollution free and it converts fuel to electrical energy at high efficiency. The use of these fuel cell electric vehicle as stationary power production unit has added to the future prospects of such systems. This will help in creating a network of decentralized small scale power production units in the grid. Such power production units can be used effectively to meet the peak power demands in the grid.This paper proposes a grid tied Solid Oxide Fuel Cell (SOFC) system. The mathematical modelling of fuel cell given literature has been analysed and a Solid Oxide Fuel Cell (SOFC) model has been simulated. The SOFC has been further connected to a boost converter and an inverter to create a grid connected power generation system. Synchronous reference frame (SRF) theory has been used to syncronise the output of the proposed system to the grid. The proposed system has also been simulated using MATLAB with its Simpower system Blockset. The performance of the proposed system is found to be satisfactory.
