1. Battery storage implementation in Sweden and sizing software development
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : 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. Pathways towards universal access to electricity in West Africa : Case study of Mali and Senegal
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Despite the vast solar potential in both Mali and Senegal, the electricity access in both countries remains one of the lowest in the world. The main problem is represented by the disparity between rural and urban settlements. In Senegal, the electricity access for rural areas was lower than 50%, while in Mali was around 35%. READ MORE

4. System impact of micro-production
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG.

5. Coordination of base station energy storage for renewable energy grid : Utilizing Base Station battery storage to stabilize grids with Variable Renewable Energy Sources
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : An increasing amount of variable renewable energy sources are being added to the world’s power grids both as an effort to reduce greenhouse gas emissions in the fight against climate change but also because some of the energy sources with the lowest levelized cost of energy are variable renewable energy sources such as wind and photovoltaics. These energy sources come with inherent difficulties since their energy production is neither constant nor entirely controllable and can cause issues for the power grids if they cause power production and consumption to become imbalanced.
