摘　　要：目的为了降低辽宁省公共机构建筑能耗,充分利用太阳能以及地热能等可再生能源,优化能源供应结构,确定2020年至2050年辽宁省公共机构能源供应中利用可再生能源的最佳技术方案.方法对辽宁省公共机构能源需求量及可再生能源比例进行设定.根据辽宁省可再生能源情况,采用方案分析法设计4种不同的能源耦合方案.建立MARKAL模型对4种方案进行模拟和预测.结果在设计的4种方案中,采用太阳能与化石能源相耦合的方案降低碳排放量最大,相比不利用可再生能源供应的基准方案降低碳排放44%.采用地热能与化石能源相耦合的方案成本最低,总投资成本约为4622.1亿元.结论辽宁省公共机构能源供应方案宜选择太阳能、地热能与化石能源相耦合的供应方案,该方案可减少辽宁省公共机构碳排放,满足绿色发展需要.In order to make full use of the resources of solar energy and geothermal energy,reduce the energy consumption of public building and optimize the energy supply structure in Liaoning Province,and the best technical scheme from 2020 to 2050 of renewable energy in energy supply structure of public building is determined.According to the energy demand of public building in Liaoning Province and the proportion of renewable energy assumed,and four different energy coupling schemes are established by scenario analysis.The four schemes are simulated and predicted by MARKAL model established.Among the four schemes,the scheme of coupling solar energy,geothermal energy and fossil energy has the largest reduction in carbon emission,which is 44%lower than the benchmark scheme with no renewable energy.The scheme of coupling geothermal energy and fossil energy has the lowest cost,with a total investment cost of 462.21 billion yuan.The energy supply scheme of public building in Liaoning Province should adopt coupling solar energy,geothermal energy and fossil energy.The scheme can reduce carbon emissions of public building and meet the needs of environmental development.
