International ClassG05D 1100AbstractA site management system (11) is provided for a power system (8) at site in a utility distribution grid (10). The power system (8) includes multiple fuel cell power plants (18) and one or more loads (14), for selective connection/disconnection with the grid (10) The site management system (11) controls the power plants (18) in an integrated manner, alternatively in a grid connected mode and a grid independent mode. The multiple power plants (18) at the site may be viewed and operated as a unified distributed resource on the grid (10). The site management system (11) provides signals representative of the present power capability (Kw Capacity—88) of each of the power plants (18), and a signal (Total Kw Capacity—95) representative of the total present power capability at the site. These power representations are used to appropriately assign power dispatch loadings to the respective fuel cells (18) in the grid connected mode and in the grid independent mode, and may also be used for load shedding.Field of SearchElectrical power distributionElectrical power generation or distribution system Substitute or emergency source FUEL CELL, SUBCOMBINATION THEREOF OR METHODS OF OPERATING Having means for active material generation or regeneration By electrical current Automatic control means Electrical output dependent Having electrical circuitry External type For plural cells CURRENT PRODUCING CELL, ELEMENTS, SUBCOMBINATIONS AND COMPOSITIONS FOR USE THEREWITH AND ADJUNCTS Having means to interchangeably connect plural individual cells or means to conectively support cell to current seeking apparatus Process of operating |
