Abstract:
1. A computer system programmed to optimize operation of a plurality of power generating units, the computer system comprising: a multi-unit optimization system including (a) a multi-unit model comprised of a plurality of unit models, each unit model associated with a respective power generating unit, and (b) a multi-unit steady state optimizer, said multi-unit steady state optimizer determining economic trade-offs between improvements in boiler efficiency and reductions of boiler and SCR NOx emissions of the plurality of power generating units, said economic trade-offs determined by determining how much NOx should be removed in the boiler using combustion optimization versus how much NOx should be removed in the SCR using SCR optimization; and a plurality of multi-component optimization systems, each multi-component optimization system associated with a respective power generating unit and including a combustion optimization system and an SCR optimization system.
