A Daily Operation Scheduling of Cogeneration System with a Thermal Storage Tank

Abstract

In this paper a numerical model of the cogeneration system is proposed for daily operation scheduling. Especially this paper describes a numerical model considered both the steam to electricity ratio and the thermal storage tank for more reasonable operation of cogeneration system. Minimum daily operation costs of topping cycle and bottoming cycle are calculated by using the proposed model. Simulation results of four cases are analyzed and compared each other. By these simulations which are similar to real operation circumstances, the validity of the proposed model is verified.
