| 摘要: |
| 在供热当量基础上，从无能量品位的污染排放角度提出等排性能系数，以作为克服能量品位的热（冷）能与电能转化的依据，并构建其数学指标。为研究等排性能系数对系统运行经济性的影响，建立包括发电成本与环境成本的冷热电多联供（CCHP）系统的多目标优化调度模型，运用隶属函数将其转化为单目标模型，并利用非线性规划方法求解。仿真结果表明，等排性能系数能准确反映能量等值转化随供能生产状态的变化及不同生产供能状态下CCHP系统的实时能耗成本。 |

| Abstract: |
| Based on the heat equivalent and from the perspective of pollution emission without energy grade，a coefficient of equal emission performance is proposed as the basis of energy conversion between heat／cool and electricity to overcome the energy grade，and it’s mathematical index is constructed. In order to study the effect of equal emission performance coefficient on economic operation of power system，a multi-objective optimization model，including generation cost，environmental cost and equal emission performance coefficient，is built for the dispatch of CCHP（Combined Cool，Heat and Power） supply system，which is then converted to a single-objective optimization model by the membership function and solved by the nonlinear planning method. Simulative result shows that，the equal emission performance coefficient can correctly reflect the variation of energy equivalent conversion along with the energy production state and the real-time energy consumption cost of CCHP under different energy production states. |
