This paper describes a daily operation scheduling method for industrial cogeneration systems that are connected to auxiliary devices. Such systems either sell electricity to a utility or buy electricity from the utility. Auxiliary devices connected to cogeneration systems include a heat storage tank, an electricity charger, an auxiliary boiler and an independent generator. The auxiliary devices can be effectively operated during the time interval of the thermal peak load or the electrical peak load. Simulation is performed in the case of bottoming cycle which produces preferentially thermal energy over electrical energy. In this paper, the modeling of cogeneration systems and auxiliary devices is described and the effectiveness of the modeling is evaluated by means of detailed simulations. A daily operation scheduling scheme is established under the operation cost of minimum level. Simulations are carried out using fuzzy linear programming
