| dc.description.abstract | The research work reported in this thesis is based on mathematical modeling of solid oxide fuel cell (SOFC) and its integration with grid. With the recent advancements in electrochemistry and the increasing demands for environment friendly energy resources, fuel cell technology has gained the major significance due to its compact size, low chemical emissions and low maintenance. Among different types of fuel cells, high temperature SOFC’s are capable for the stand alone high power production and grid-tied applications. Also the increase in demand for electric power, the distributed generation (DG) has attained much attention. DG utilizes alternate energy resources such as photovoltaic systems, wind energy systems and fuel cells. SOFC has proved to be a promising technology for distributed power generation with compact size, high power efficiency and absence of moving parts. SOFC is used as a reliable energy source in case of steady operations, but it shows slow response in case of transient conditions. Researchers have been working from past few years on modeling of SOFC to visualize its behavior under certain conditions. Most of the research articles do not include the detail of losses in SOFC which must be included in the equivalent model for analyzing the actual behavior of the SOFC over the time. In this research work, a mathematical model for a SOFC accounting for thermodynamic limits, effect of temperature and pressure variations is formulated to evaluate and visualize its actual characteristics. Activation, ohmic and mass transport over potentials are also included in the model. For connection of SOFC with grid, an intermediate module (Power Conditioning Unit) is proposed. Power Conditioning Unit (PCU) improves the slow response of SOFC and also steps up the DC voltages. It consists of a boost converter and a 3-phase inverter. PCU sets technical challenges in order to integrate SOFC with the utility grid. The overall modeling and integration of SOFC with the utility grid covers, the detailed representations of equivalent model of SOFC, power electronic modules, transformers and the grid integration technique. The proposed model is implemented in MATLAB-SIMULINK. It can be utilized for visualization of optimum characteristics and operation of grid integrated SOFC stack and its behavior under various operating conditions. | |
