Modelling of Carnot Batteries with Latent Thermal Energy Storages

该项目的全球目标是确定、建模、模拟和评估基于潜热储能（TES）的卡诺电池（CB）的概念，该概念可以补偿风能和太阳能发电的波动性。将定义实际运行场景并以此为基础，其中特别包括部分负荷间歇运行和可变运行状态。第一个三年资助期的全球目标将通过反方法分几个步骤实现，具体目标G1至G6定义如下：G1：确定潜在TES的CBs的操作方案。G2: TES的设计和布局，推导可用于CB整体系统仿真的TES简化模型。G3：通过基于逆方法的系统模拟，确定基本参数并了解其对CB效率的影响。G4：推导出有利于CB系统配置的特定参数组合。G5：采用详细模型对选定系统进行火用分析，对组件和子过程的损失进行透明量化。G6：确定在多标准评估中要考虑的选定系统的成本和技术准备水平。

The global objective of the project is to identify, model and simulate, and evaluate concepts for Carnot Batteries (CB) based on latent thermal energy storage (TES), which can compensate for the volatility of wind and solar electric power generation. Realistic operation scenarios will be defined and used as a basis, which in particular also include intermittent operation at partial load and variable operating states. This global objective for the first three-year funding period will be achieved via an inverse approach in several steps, for which the following specific goals G1 to G6 are defined: G1: Determination of operation scenarios for CBs with latent TES. G2: Design and layout of the TES and derivation of simplified models of the TES that can be used in the CB overall system simulation. G3: Identification of the essential parameters and understanding of their influence on the CB efficiency by systematic simulations based on an inverse approach. G4: Derivation of specific parameter combinations that lead to favorable CB system configurations. G5: Transparent quantification of losses in components and sub-processes applying an exergy analysis of the selected systems with a detailed model. G6: Determination of the costs and the Technology Readiness Level (TRL) of the selected systems to be taken into account in a multi-criterial evaluation.
