Vector Control of Fuel Cell Based GridConnected Inverter

Electrical energy consumption increases day by day so we should find alternative means to generate electrical energy to meet the demand in addition to existing conventional generation facilities. For this distributed generation (DG) will definitely going to take a key role in the energy supply. Presently various technologies are available as DG, they are micro-turbines, photovoltaic cells system, fuel cells system and wind energy systems. Out of these technologies fuel cell have becoming more popular due to its characteristics like cleanliness, portability and suitability for electricity and heat generation. In this paper, model of Solid Oxide Fuel Cell (SOFC) is presented. As fuel cells operate at lower voltages so there is a need of DC-DC boost converter to boost. Then the boosted voltage inverted by using DC-AC converter known as grid-connected inverter in order to inter connect to the utility grid. The control strategy of this model is vector control (VC) method. VC method is use for the generation of DC-AC converter switch pulse. MATLAB/SIMULINK is used to validate the modeling and simulation of fuel cell generation and power conditioning unit. Journal of Green Engineering, Vol. 8 3, 201–218.
