质子交换膜燃料电池(proton exchange membrane fuel cell，PEMFC)热电联供(combined heat and power，CHP)系统作为一种建筑供能新手段，可有效降低建筑运行能耗、推动能源绿色低碳转型。针对北方地区住宅建筑电热需求大且热电矛盾突出，全年负荷波动大等特点，以北京市为代表，利用 DeST 软件对住宅建筑进行负荷分析并搭建燃料电池热电联供系统模拟平台，研究不同参数对联供系统性能的影响;以负荷特性和参数分析结果为依据，设计一年不同时段下北京住宅建筑管理策略:冬季采用"以热定电"，其余季节均采用"以电定热";与基线系统相比，在春、夏、秋、冬4个典型日中联供系统天然气耗气量分别减少了39。16%、31。63%、36。01%和 14。04%，对热电联供系统用于未来建筑供能具有一定借鉴意义。
Simulation Study of Fuel Cell CHP System and Energy Demands Analysis for Residential Buildings in Beijing
As a new technology of building energy supply,a combined heat and power(CHP)system based on proton exchange membrane fuel cells(PEMFCs)can effectively reduce the energy consumption of building and promote the green and low-carbon transformation of energy.The residential buildings in northern China have the characteristics of large demand for energy,outstanding contradiction between heat and electricity;and the load fluctuates greatly throughout the year.Therefore,taking Beijing as a representative of a cold region,the DeST software is used to accurately analyze the load of residential buildings and a suitable simulation platform is set up for fuel cell CHP systems.The effects of different parameters on the system performance are studied.Based on the analysis results of load characteristics and parameters,energy management strategies are analyzed in residential buildings in Beijing at different seasons.The"following the thermal load"strategy is adopted in winter;the"following the electric load"strategy is adopted in other seasons.Compared with the baseline system,the gas consumption of the PEMFC-CHP system in different seasons drops by 39.16%,31.63%,36.01%and 14.04%,respectively.It has reference significance for the use of FC-CHP system in future building energy supply.
