摘要/Abstract

摘要： 综合供能系统可同时为用户提供冷热电3种负荷需求，其有联供和分供2种供能方式。首先基于全寿命周期理论，构建了包含能源生命周期内温室气体处理费用和系统运行成本的综合评估指标，通过比较综合供能系统的分供运行、联供运行下以热定电模式和以电定热模式在综合指标上的表现，得到基于冷热电负荷比例上的综合供能系统最优运行模式评估方法。最后将此评估方法评价算例系统在冬、春秋、夏3种典型日下分供运行、联供运行下以热定电和以电定热3种模式的优劣，得出其最优运行模式不再是单一的运行模式，而是由负荷比例决定的混合运行模式。经验证，所提方法可以方便有效地评估及优化综合供能系统的运行模式。

Abstract: The integrated energy supply system can provide loads for cooling, heating and power for users at the same time, and there are two operation modes: CCHP operation and separation production. Firstly, based on the life cycle theory, a comprehensive evaluation index system is constructed including greenhouse gas treatment cost in the energy life cycle and system operation cost. By comparing the performance between separation production and CCHP in terms of comprehensive evaluation index under the modes of CCHP-FHL and CCHP-FEL, an evaluation method of the optimal operation mode is obtained based on the load of cooling, heating and power. Finally, the evaluation method is applied in an example system to evaluate the performance of CCHP-FHL and CCHP-FEL modes under separation production and CCHP operation in 3 types of typical days in winter, spring & autumn, and summer respectively. It can be concluded that the optimal operation mode is no longer a single operation mode, but a mixed operation mode determined by the proportion of cooling, heating and power loads. It is verified that the evaluation method can be used to evaluate and optimize the integrated energy supply system conveniently and effectively.

Key words: integrated energy supply system, CCHP, separation production, life cycle theory, load ratio, evaluation method
