In order to enable an advanced self-healing energy management of the Hybrid Battery Energy Storage System (HBESS), it is important to have an accurate estimation of the power electronics interface lifetime. Therefore, this results develops a lifetime estimation framework for the power electronics converters used in the HBESS.
Hybrid Energy Storage System (HESS) prototype that focuses on physics-based failures in order to evaluate the design robustness. By incorporating physics-based degradation into reliability prediction modeling, the lifetime of the designed modular power electronics topology is measured.
The objective is to assess the lifetime and reliability of the power electronics converters in the HBESS.
The lifetime estimation framework was developed focusing on physics-based failures in order to evaluate the design robustness of the power electronics converters. By incorporating physics-based degradation into reliability prediction modeling, the lifetime of the designed modular power electronics topology was measured, considering the different load profiles in the project.
The result is a comprehensive lifetime estimation framework for the power electronics interfaces. The lifetime estimation framework will be used in the self-healing energy management algorithm, in order to control the system towards higher reliability and lifetime. This result enable the system to work in an optimized way towards higher lifetime and reliability, therefore reducing the maintenance and operating costs of the system.
