Large-scale energy storage systems are critical on the road to electrifying and decarbonizing the grid's energy. However, these systems consist of numerous individual cells and various ancillary systems, where monitoring and controlling cell-level behavior become challenging due to potential cell-to-cell variations. In a recent issue of Applied Energy, Reniers and Howey built a digital twin for a 1 MWh grid battery system consisting of 18,900 cells and conducted a 10-year simulation, demonstrating the significance of battery system monitoring and control in mitigating cell-to-cell variations over the battery's lifespan.

解锁大规模电池数字孪生的主要障碍

大型储能系统在电网能源电气化和脱碳的道路上至关重要。然而，这些系统由许多单独的细胞和各种辅助系统组成，由于潜在的细胞间差异，监测和控制细胞水平的行为变得具有挑战性。在最近一期的Applied Energy中，Reniers 和 Howey 为由 18,900 个电池组成的 1 MWh 电网电池系统构建了一个数字孪生体，并进行了 10 年的模拟，证明了电池系统监测和控制在缓解电池到电池方面的重要性电池寿命的变化。
