8.2.4 Fuel Cell Power Conversion for Supplying a Load Operating in Parallel With the Local Utility (Utility Interactive) Figure 8-16 shows the block diagram of a fuel cell power conversion scheme supplying a load in parallel with the utility. In this configuration, the peak power (as well as the inrush current) demanded by the load is provided by the utility. By paralleling the fuel cell power output to the utility, the following advantages can be realized: • Power conversion rating is same as the fuel cell • Peak power (as well as the inrush current) demanded by the load is provided by the utility • A constant fuel cell power level can be set. While in the utility connect mode, the voltage is set by the utility and current control is used to manage the power flow from the fuel cell. In the event of a utility failure, the fuel cell system does not have the ability to supply inrush current to loads such as for motor starting etc. Special circuit breakers to isolate loads up to the capacity of the fuel cell are necessary. Furthermore, the utility interconnection must conform to IEEE Standard P1547 to prevent energizing a section of the utility by the fuel cell source under utility fault conditions (islanding).

IEEE Standard P1547 [12] outlines the criteria and requirements for interconnecting distributed resources such as a fuel cell power plant with the electric power system. It provides requirements relevant to the performance, operation, testing, safety considerations, and maintenance of the interconnection. Islanding should be avoided at any cost: that is a condition in which a fuel cell power plant energizes a portion of the electric power system when the utility power is disconnected. In other words, the fuel cell power connected to the utility must be disconnected immediately in case of utility failure. In general, a fuel cell power converter that has to be interfaced with the utility should meet the following requirements: When a distributed resource such as a fuel cell is synchronized with the utility, it should not cause the area electric power system voltage to fluctuate more than ±5 percent 8-37PDF Image | Fuel Cell Handbook (Seventh Edition)
