J912e: Typical step response of a micro-turbine
Transient changes in load power demand may result from faults in transmission line or load switching. For instance, a 75-kW Honeywell micro-turbine took about 35 s to respond for a 50%change in power demand under the grid-connected mode of operation.On the other hand, some fuel cells require about 10 s for a 15% change in power output.Furthermore, a fuel cell also has a recovery period of a few minutes to establish equilibrium before it can meet another step change in power output. The typical response that can be expected of a micro-turbine for a step change in load demand is illustrated in Figure. In the figure, PL denotes the load power demand, PS is the response of the micro-turbine, and (PL-PS) is the short age in power that needs to be supplied through some means. Inthe grid-connected mode of operation, the grid supplies the shortage in power until the micro-source responds to a step changein power demand. However, in the island mode of operation, this sudden demand can be met only if
additional storage is included in the MSDG system.
