摘要
建筑领域的节能减碳对于推动我国实现“碳达峰、碳中和”的目标至关重要。针对建筑终端用能去碳化、经济化的需求,提出一种零能耗建筑(zeroenergybuilding,ZEB)系统电-氢-热双层能量优化调控方法。首先,根据建筑用能特性,构建含风、光、氢的零能耗(零碳)建筑能源拓扑结构;其次,将零能耗建筑系统能量管理以不同时间尺度划分为经济优化层与实时功率调控层,针对经济优化层,提出电-氢-热经济优化管理方法;针对实时功率调控层,提出基于状态控制的实时功率偏差修正策略;最后,通过典型日算例仿真,验证了文中所提零能耗建筑系统能量优化调控方法的有效性。同时,考虑电解槽和燃料电池运行余热回收利用,系统综合运行效率从72.9%提升至87.5%。
Energy saving and carbon reduction in the field of construction are essential for China to achieve the goal of "peak carbon emissions and carbon neutrality". In order to meet decarbonization and economy of building terminal energy consumption, this paper proposed an optimal control method of electricity-hydrogen-heat double-layer energy for zero energy building system. Firstly, this paper constructed a zero energy(zero carbon) building energy topology structure containing wind-photovoltaic-hydrogen according to the energy use characteristics of the building. Secondly, the energy management of zero energy building system was divided into economic optimization layer and real-time power control layer according to different time scales. For the economic optimization layer, the electricity-hydrogen-heat economic optimization management method was proposed;for the real-time power control layer, the real-time power deviation correction strategy based on state control was proposed.Finally, the effectiveness of the proposed method was verified by simulation of a typical daily example. Also, considering the recovery and utilization of waste heat from the operation of electrolyzers and fuel cells, the overall operating efficiency of the system has increased from 72.9% to 87.5%.
