研究了冷热电联产热电联产系统的能量优化管理问题。能源系统由燃气轮机、吸收式制冷机和热回收锅炉组成。提出了一个简单的线性规划模型，以确定使热电联产系统总能源成本最小的最优策略。结果表明，该系统的最优运行取决于所要满足的负荷条件。从能源成本的角度出发，表明有时运行水轮机可能不是最优的。这是在电-气成本比非常低的情况下发生的。
This paper deals with the problem of optimal energy management of cogeneration system for combined cooling, heating and power production (CCHP). The energy system consists of a gas turbine, an absorption chiller and a heat recovery boiler. A simple linear programming model is presented to determine the optimal strategies that minimize the overall cost of energy for the CCHP system. It is shown that the optimal operation of this system is dependent upon load conditions to be satisfied. In view of energy cost, it is shown that sometimes it may not be optimal to operate the turbine. This is the case when the electric-to-gas cost ratio is very low.
