Control Strategy for a Solid Oxide Fuel Cell Fueled by Natural Gas Operating in Distributed Generation

The paper presents a control strategy concept for a Solid Oxide Fuel Cell (SOFC) to work in Distributed Generation. The control strategy is based on several factors and directs the operation of the SOFC in the context of changes occurring in the market, while taking into account the operating characteristics of the power unit. The control strategy is defined by an appropriate objective function: for example, work at maximum profit, maximum service life, etc. The results of simulations of a fuel cell at chosen loads are presented. Daily changes in the prices of fuel and electricity are factored into the simulations.
