Research on Fuel Cell Power Generation System Model with Grid

The paper take the solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) as the object, studies the influence of the fuel cell on load characteristics of the distribution network. Structures based on Matlab simulation platform contains the SOFC typical distribution network, and a series of transient simulation was conducted, results indicate that the SOFC power generation system can be describe in its equivalent model based on the URL equivalent circuit-order differential equation of state. On this basis, the access to the distribution network SOFC power generation system regarded as power consumption of the negative dynamic load, proposed containing the SOFC can be to the equivalent the GSLM model containing the SOFC described distribution grid load characteristics.
