区域能源系统技术方案分析

Technical scheme analysis of a district energy system

指出区域能源可采用燃气分布式、地源热泵、蓄能以及'多能协同'多种方案。在不同负荷工况下,按照不同时刻各种供能形式的成本高低进行优先排序,并综合考虑地源热泵地源侧取放热平衡、蓄能取放热平衡,给出了'多能协同'的运行策略;通过投资、运营成本、收入的综合测算对比分析,认为'多能协同'方案具备市场竞争力。

Points out that district energy sources cover gas distribution,ground-source heat pump,energy storage and'multi-energy coordination'.Prioritizes the district energy sources according to the costs of various energy supply forms at different times under different load conditions.Presents the operation strategy of'intelligent coupling'after considering the heat balance of the ground-source heat pumps and energy storage.Compares and analyses the comprehensive calculation of investment,operation cost and income,suggests a'multi-energy coordination'scheme with market competitiveness.
