1. Battery storage implementation in Sweden and sizing software development
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Due to the rampant growth of the penetration of renewables into the electrical grids across the world, more challenges appear in the way to assure the optimal operation of the energy system. More particularly, in the case of Sweden, the nuclear power decommissioning tendency and the 100% renewable energy target by 2040, set two strong additional motivations for the rise of issues regarding variability, uncertainty, stability, balancing and quality in the grid.

2. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). LÄS MER
3. State-of-safety (SoS) data-driven assessment for utility-scale lithium-ion operating BESS
Master-uppsats, KTH/EnergiteknikSammanfattning : The thesis project presented in this report proposes a methodology to implement the safety assessment of an operating electricity storage plant using a data-driven approach. This methodology is applied to one practical case. LÄS MER
4. Supervised Algorithm for Predictive Maintenance
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Predictive maintenance plays a crucial role in preventing unexpected equipment failures and maintaining assets in good operating conditions in various systems. One such scenario where predictive maintenance has been widely used is in battery management systems for electronic vehicles based on lithium batteries, where the risk of failure can be reduced by predicting the remaining useful life of the lithium battery.

5. Physics-Based Modelling for SEI and Lithium Plating During Calendar and Cycling Ageing
Master-uppsats, KTH/KemiteknikSammanfattning : Målet med projektet var att undersöka samt implementera en fysikbaserad DFN modell för att simulera kalender samt cyklingåldrande av litiumbatterier som används i elbilar. Den fysikbaserade modellen var konstruerad baserad på ett Python biblioteket vid namn PyBaMM, vilket till skillnad från datadrivna modeller ger essentiell information om de kemiska processerna inuti batteriet.
