Simulation on the improvement of the distributed power system stability using fuel cell plant

The continuous service for customers is complicated process in distribution system, when the system apparatus and customers are get affected by various large number of outages which caused by improper maintenance of system utilities and some environmental factors results block-out regions in the systems. The impact of distributed generation on distribution system, stability will be negligible when connected in small amounts. However, if it´s penetration level become higher, distributed generation may start to influence the dynamic behavior of the system as a whole. So, the fuel cells (SOFC) are used as distributed generation system which is penetrates in distribution network to enhance the continuous service for customers. In this paper, we are analyzing the system stability by describing the dynamic modeling of fuel cell to the system utility grid by using MATLAB/SIMULINK.
