| 摘要: |
| 详细分析系统能量流特性，提出刻画冷热电联供（CCHP）系统在“以热定电”和“以电定热” 2种运行策略下的能量流函数。为提升CCHP系统的经济环保效益，建立其经济环保调度优化模型，目标函数包含燃料成本、购电成本及考虑污染气体排放需缴纳惩罚费用的环境成本，能量流函数作为能量平衡等式约束。算例仿真结果表明，所提能量流函数及模型可实现CCHP系统的优化调度，从而降低生产成本，改善环境效益，提高能源利用水平。 |

| Abstract: |
| The energy flow characteristics of CCHP（Combined Cooling，Heating and Power） system are analyzed in detail and the energy flow function is proposed for its two operational strategies：thermal load dominant mode and electric load dominant mode. In order to improve its economic and environmental efficiency，an optimal economic and environmental dispatch model is built，which includes the fuel cost，power purchase cost and pollution emission penalty as environmental cost in its objective function and takes the energy flow function as its energy balance equality constraint. Case simulation shows that，the proposed energy flow function and model optimizes the dispatch of CCHP system，reduces the productive cost，improves the environmental efficiency and enhances the energy utilization level. |
