摘要

为应对能源互联网中日益严重的绿电弃电问题

提出采用熔盐蓄热回收绿电弃电的热电联产共享储热系统。设计熔盐蓄热制主蒸汽(S1)和熔盐蓄热制工业蒸汽(S2)2种热电联产共享储热系统构型

建立变工况仿真模型、分析模型以及技术经济性评估模型

并提出往返效率、日利润增量和动态投资回报期评价指标

以分析2种系统构型经济性和敏感性。结果表明:方案S1和S2回收绿电弃电的往返效率分别为54.34%和43.36%;热电联产共享储热系统回收绿电弃电提高了系统整体的技术经济性

在原系统基础上采用方案S1和S2的日利润增长率分别为1.94%和2.44%。

Abstract

To cope with the increasing green power curtailments in energy internet

a cogeneration shared heat storage system using molten salt heat storage to recover green power curtailments was proposed. Two system configurations were designed

namely

using molten salt heat storage to gain main steam (S1) or industrial steam (S2). Simulation models

exergy analysis models

and techno-economic evaluation models were established. Besides

evaluation indexes

including round-trip exergy efficiency

daily profit increment

and dynamic payback period

were proposed to analyze the economics and sensitivity of two systems. Results show that the round-trip exergy efficiencies of S1 and S2 are 54.34% and 43.36%

respectively. The cogeneration shared heat storage system improves the overall technical economy

and the daily profit growth rates of using S1 and S2 on the basis of the original system are 1.94% and 2.44%

respectively.
