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.

该项目的全球目标是识别、建模、模拟和评估基于潜热储能（TES）的卡诺电池（CB）概念，该概念可以补偿风能和太阳能发电的波动性。将定义并使用实际操作场景作为基础，其中特别包括部分负载和可变操作状态下的间歇操作。第一个三年供资期的这一全球目标将通过逆向方法分几个步骤实现，为此确定了以下具体目标G1至G6：G1：确定具有潜在TES的CB的操作方案。G2：TES的设计和布局以及可用于CB整体系统仿真的TES简化模型的推导。第三代：识别的基本参数和了解他们对CB效率的系统模拟的基础上的逆方法的影响。G4：导出导致有利CB系统配置的特定参数组合。G5：通过详细的模型对选定的系统进行有效能分析，透明地量化组件和子流程中的损耗。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。
