Solid Oxide Fuel Cell Interfaced with a Three-Phase Power System

Solid oxide fuel cells (SOFCs) have gained significant attention as a clean and efficient energy conversion technology. Their ability to directly convert the chemical energy in fuels, such as hydrogen or hydrocarbons, into electrical energy with high efficiency and low emissions makes them promising candidates for distributed power generation. It consists of a phase infinite bus through an IGBT inverter. The interface between the SOFC and the power system considers key factors such as voltage and frequency regulation, power quality, and grid stability. Various control schemes are evaluated for maintaining the balance between the power generated by the SOFC and the demand from the grid, while also addressing transient responses and load variations. Additionally, the impact of the SOFC system on the overall grid performance is assessed, including the potential for grid support functions such as voltage regulation and frequency response.
