含有氢能汽车和储能的新型光伏建筑能源系统建模

Modelling of a novel photovoltaics building energy system considering hydrogen vehicles and energy storage

针对近零能耗建筑和氢能汽车与储能技术的集成,提出了一种新型低碳光伏建筑综合能源系统数学模型.该系统以分布式光伏作为可再生电力来源,并含有电解-储氢和储冷储热系统.模型考虑建筑附属氢能汽车(Hydrogen Vehicles,HVs)向系统的供能过程,并针对汽车的行驶特性,利用蒙特卡洛方法建立汽车调度模型.最后生成了一个混合整数线性优化问题,并通过具体算例,分析了系统在三个典型日的电-热-冷调度结果.算例表明:HVs与建筑系统集成将有助于降低系统的交换功率,光伏装机量的提升与储能设备的应用则有助于降低系统碳排放量.

In order to integrate hydrogen vehicles and energy storage technology with nearly-zero energy buildings,a novel mathematical model of low-carbon photovoltaic building integrated energy system was proposed,which used photovoltaic as renewable power source,and contained electrolysis-hydrogen storage system and cool/heat storage system.In the model,hydrogen vehicles(HVs)attached to buildings were included in the system energy scheduling process.According to the driving characteristics of vehicles,the vehicle scheduling model was established through Monte Carlo method.Finally,a mixed integer linear optimization problem was generated,and the power-heat-cold dispatching results of three typical days were analyzed through a case study.The case study shows that the integration of HVs and building will help to reduce the exchange power between the building and public grid,and the improvement of photovoltaic installed capacity and the application of energy storage system will help to reduce the total carbon emission of the system.
