As a practical example to show the capability of this framework, the life consumption (LC) of power semiconductors (IGBTs and diodes) is determined considering both solar panel and lithium-ion battery degradation. Different panel degradation rates can be defined to the framework. The battery degradation is calculated by a closed-loop approach so that the battery degradation is adjusted based on the determined cycling and calendar aging. The outputs are obtained for three cases: (1) no degradation, (2) only PV degradation, and (3) both PV and battery degradation. The results showed that by considering the battery degradation, the battery DC-DC converter’s switches will experience 14% lower LC compared to the case with both PV and battery degradation models, while the switches within the PV inverter have 2.3% higher LC when considering the battery degradation. | Keywords: | Battery / Batteries;Lifetime;Time Resolution;Estimation;Mission Profile;Power Devices | Document URI: | http://hdl.handle.net/1942/37490 | ISBN: | 3936338787 | DOI: | 10.4229/EUPVSEC20212021-6BV.5.4 | Category: | C2 | Type: | Proceedings Paper |
