The dynamic of a micro-grid that consists of engine generator and sixteen fuel cells was clarified by the transfer function model using the actual data of power generators. The microgrid was composed from a 3kW engine generator and 1kW fuel cells, and the dynamic characteristics of the grid was analyzed using the energy demand model in February of cold region. As a result, the settling time (Time to converge on ±5% of limit of an output target) of a micro-grid is 15 seconds from 10 seconds. The control parameter of a fuel cell system influences in the settling time and overshooting of a micro-grid strongly. Since the excess and deficiency of electric power can be covered each other if two or more fuel cells are connected with a gird, the instant electric power demand load peak can be distributed. Compared with the number of fuel cells in the case of installing independently, the number of installation of a micro-grid system is reducible.
