Abstract :
This paper presents modeling and control of a hybrid Photovoltaic (PV), Diesel-Engine Generator (DEG) - Fuel Cell (FC) system connected to electric grid. A case study on impact of FC operation on the frequency stability of electric grid has been carried out. The model of fuel cell system includes a fuel cell generator, electrolyzer and a hydrogen storage facility. The limits on hydrogen volume due to limited storage capacity have also been incorporated. The modeling of photovoltaic is also presented and analyzed for a time period of 24-hours with varying solar radiation and temperature. Results of simulation indicate that FC system can contribute to frequency stability in both cases when the load increases and also when the load drops. This feature of FC system will be helpful if it is operated along with a hybrid Wind-PV System.
