考虑储能和需求响应的高比例可再生能源综合能源系统建模

发布时间：2021-08-31 19:20

　　人类的日常活动需要不同形式的能源,例如电力、热能和天然气。化石能源产生了两种最常用的能量载体（电和热）,而它也是造成全球变暖的主要原因。由于地质资源的有限性和气候变化,化石能源变得日益稀少和昂贵。这迫使人们转向低碳、取之不尽、环境友好、便于获取且有益于公共卫生的可再生能源。相比其他可再生能源,风能和太阳能因为无碳特征而被大量开发和利用。但是,风能和太阳能的随机性使其被称为波动性可再生能源,它们的不确定性和可变性会破坏电力系统的稳定性。这项研究首先在中国的电网中加入了储能和需求响应,通过减少燃料消耗和将临界过剩发电量保持为零来消纳更多的波动性可再生能源。传统上,电能和热能载体是独立运行的,但转换过程中的热量损失导致其运行效率低下。多能源载体的耦合对于解决上述问题至关重要,而耦合可以基于新近的技术如热电联产、热泵、需求响应和储能等。能源枢纽中的耦合节点可以促使电力系统向综合能源系统进行提高经济效益、灵活和无碳的能量转换。因此,这项工作进一步提出了智能能源枢纽的方案,通过使用能源系统分析工具Energy PLAN对中国2020年的电力、区域和个体供热综合能源系统进行建模。通过添加热泵、储热元...
