This patent describes a steam and power cogeneration system including a network of fluid flow for passing a demand of steam there-through at respective higher and lower pressures. It embodies at least two steam-to-power converter units operatively connected between corresponding ones of the flow lines at different pressures, and at least two pressure reducing valves operatively connected between corresponding ones of the flow lines at different pressures. The system comprises means for optimizing power generation by the steam-to-power converter units and for optimizing steam flow through the network in accordance with a predetermined concurrent steam and power demand; the optimizing means being operable in relation to a plurality of predetermined planes of control each defined by a given status and configuration of the network; means being provided responsive responsive to a change of actual network status and configuration for selecting optimization by the optimizing means by reference to a new plane of control associated with the new and actual status and configuration of the network; means for controlling the distribution of steam through the network and concurrent generation of power in accordance with the optimizing results for the new plane of control.
