Hybrid Hydrogen Home Storage for Decentralized Energy Autonomy

To determine the cost minimal supply system and its operation for a self-sufficient building, a Mixed Integer Linear Program is developed within the modelling framework FINE. It uses the optimisation modelling language Pyomo and is available open source. The model represents decisions on the buildings’ energy system structure (technology selection), sizing (capacity of energy supply units) and operation for one representative year in a set of linear equations with continuous and binary variables. Sizing and operation for a self-sufficient supply has been optimized for the representative year with one-hour time-steps towards a goal function representing equivalent total annual costs.

为了确定自给自足建筑的最低成本供应系统及其运行机制，本研究在FINE建模框架下开发了一种混合整数线性规划模型。该模型采用优化建模语言Pyomo，并作为开源软件提供。模型通过一组包含连续和二元变量的线性方程，表示建筑能源系统结构（技术选择）、规模（能源供应单元容量）以及一年内代表性的运行决策。针对自给自足供应的规模和运行，已在代表性年份内以一小时为时间步长对等效年度总成本的目标函数进行了优化。
