摘要
分布式综合能源系统是提高清洁能源使用比例,实现碳减排和碳中和目标的一种配套技术.因此,针对负荷密集区冷热电负荷供需矛盾问题,提出储能协调下的负荷密集区分布式综合能源系统,并构建数学模型.其次,确立考虑系统经济、能耗、环境性能的多目标优化模型,利用层次分析法确定不同优化指标之间的权重关系.建立由住宅、办公、酒店、商场四类建筑组成的负荷密集区建筑模型,分别对四类建筑全年的逐时冷热电负荷进行模拟.最后,对比分析四类建筑分别单独设置供能系统和考虑四类建筑负荷耦合互补设置一套供能系统时的系统容量配置优化以及在相关政策影响下的系统性能.结果表明:无论是否加入储能系统,考虑四类建筑负荷耦合互补设置一套供能系统时的系统性能优于四类建筑分别单独设置供能系统的性能.
Abstract
Distributed integrated energy system(DIES)is considered to be a supporting technology to increase the proportion of clean energy use and achieve goals of carbon emission reduction and carbon neutrality.Therefore,aiming at the contradiction between supply and demand of cooling,heating and electric load in load intensive areas(LIAs),DIES in LIAs under energy storage coordination is constructed.Secondly,a multi-objective optimization model considering economy,energy and environmental performance is established.The weight of different indexes is determined by analytic hierarchy process.Then,the building model of residential,office,hotels and shopping buildings are employed and hourly cooling,heating and electric load are simulated.Finally,the system capacity allocation optimization analysis and system performance analysis under the influence of policies are compared and analyzed when four types of buildings in LIAs are separately set up with DIES and the four types of buildings are coupled and complementary set up with DIES.Draw conclusions:regardless of whether the energy storage system is added,when LIAs is as a whole,the overall optimization results of DIES in LIAs are better than the classification optimization results when DIES is optimized separately for each type of building.
