Abstract

In a plant including a multiplicity of energy conversion units which together supply load upon demand to a given process through a common junction, a system is included to economically optimize the load distribution among the multiple units dynamically during the transition of process load demand from one state to another such that when the process load supply reaches the other process demand state, the energy conversion units are substantially in their economically optimum individual load generating states. Typical unit load dispatching plants may include a boiler house in which a multiplicity of boilers are coupled to a common header for supplying stream flow to the particular process, a power turbogeneration system in which a multiplicity of turbogenerating units supply power to a power system network through a common bus and a heat exchange industrial process in which a multiplicity of power-driven compressors are used together with corresponding chiller units for maintaining the temperature of a common coolant under varying coolant flow demand conditions.
