摘要

为实现综合能源系统的可持续性评价

引入能值指标来描述系统的可持续性发展水平。构建了基于光气储互补的综合能源系统

以能值分析方法中的能值可持续性指数最大为目标函数

优化设备的容量配置。基于热跟随(FTL)和电跟随(FEL)2种运行策略

在传统能值分析方法的基础上

考虑系统全生命周期的材料消耗和污染物排放成本

应用遗传算法寻找综合能源系统的最优容量配置

并对2种运行策略下的能值性能进行分析比较。结果表明:综合能源系统采用FTL和FEL策略时的能值可持续性指数分别为2.85和2.06

且FTL策略下的能值可持续性指数比FEL策略下高出38.35%

可持续性更好。

Abstract

To enable a sustainability assessment of integrated energy systems

an emergy indicator has been introduced to describe the sustainable development level of system. An integrated energy system based on photovoltaic-gas-storage complementarity was constructed

with the maximization of the emergy sustainability index (ESI) in emergy analysis methods set as the objective function to optimize the equipment capacity allocation. Based on two operation strategies

namely following the thermal load (FTL) and following the electric load (FEL)

and considering material consumption and pollutant emission costs over the full life cycle of system in addition to traditional emergy analysis methods

a genetic algorithm was applied to identify the optimal capacity configuration of the integrated energy system

and the emergy performance under the two strategies was analyzed and compared. Results reveal that the ESI of the integrated energy system is 2.85 under the FTL strategy and 2.06 under the FEL strategy. The ESI under the FTL strategy is 38.35% higher than that under the FEL strategy

indicating better sustainability.
