Optimum scheduling procedure for cogenerating small power producing facilities

A comprehensive model of a small power-producing facility (SPPF) is discussed to determine its optimum operational schedule under utility energy-spot-pricing policies. The model is particularly well suited for SPPFs with both topping and bottoming cogeneration cycles in that the various thermal energy flows are explicitly modeled along with the electrical energy flows. The optimum scheduling algorithm is based on a linear programming method that provides for the explicit inclusion of the various thermal and electrical operating constraints. A realistic performance index, based on the true SPPF revenues and costs, is used in the linear programming procedure
