A site management system () is provided for a power system () at site in a utility distribution grid (). The power system () includes multiplefuel cellpower plants, e.g., fuel cells,() and one or more loads (), for selective connection/disconnection with the grid (). The site management system () controls the power plants () in an integrated manner, alternatively in a grid connected mode and a grid independent mode. The multiple power plants () at the site may be viewed and operated as a unified distributed resource on the grid (). The site management system () provides signals representative of the present power capability (Kw Capacity&#x2014;) of each of the power plants (), and a signal (Total Kw Capacity&#x2014;) representative of the total present power capability at the site. These power representations are used to appropriately assign power dispatch loadings to the respectivefuel cellspower plants() in the grid connected mode and in the grid independent mode, and may also be used for load shedding.

Control of multiple power plants at a site to provide a distributed resource in a utility grid

A power system () is provided for economically supplying uninterrupted electrical power to one or more critical loads (). One or more fuel cell power plants () provide one substantially continuous source of power, and a utility grid () provides another source of power. The fuel cell power plants () areadapted to be, and are,normally substantially continuously connected and providing power to, the critical load(s) (). A rapidly-acting static switch () selectivelyconnects anddisconnectsand reconnectsthe grid power supply () to the critical load(s) () and with the fuel cell power plant(s) ()for abnormal and normal grid operation, respectively. A switch controller () controls the state of the static switch () toconnect the grid power source () with the critical load(s) () and therapidly ()fuel cell power plant(s) ()during normal operation of the grid (), and to rapidly (less than 4 ms) disconnect the grid power source () from the load(s) () and the fuel cell power plant(s) () when operation of the grid () deviates from normal beyond a limit.each include power conditioning systems ()()()().
