What We Do
Swiftly gaining ground as Sweden's industry leader in battery storage and expanding rapidly in selected European markets, Flower is on a mission to enable the energy system of tomorrow.
With an industry-leading AI-powered platform at its core, our service includes stabilizing the energy system by enhancing predictability and flexibility for both energy producers and consumers. By combining pioneering technology with a portfolio of flexible energy assets, we break new ground towards a fossil-free energy system, allowing clean energy to power society.
Who We Are
Flower is Flexible Power. We are a next-gen energy company leveraging AI and machine learning to make renewable energy stable and always available – even when the sun isn't shining and the wind isn't blowing.
Through smart optimization and trading of energy assets like wind and solar farms, battery systems, and EV chargers, we make renewable energy reliable and predictable, leading the charge towards the energy system of tomorrow.
About the Master Thesis subject:
Grid‑scale BESS are increasingly important for balancing the power system, but in practice their performance depends on many interacting factors: power level, temperature, system efficiency, auxiliary loads (HVAC, control systems, etc.) and battery state of health (SoH).
Being able to predict how energy availability is changing due to these parameters is crucial when using batteries to trade on power and energy markets in order to avoid costly fees and deliver accurately on our promises. In this thesis, you will use real telemetry from Flower's BESS to figure out how we can improve the trading and optimization of grid-scale battery assets.
What You'll Do:
The goal is to build a data‑driven understanding – and preferably a simple model – of how BESS resources behave under real operation.
Example tasks:
- Perform data analysis to characterize auxiliary loads for assets in our portfolio.
- Make use of the existing data set to improve the team's understanding of optimal BESS operation.
- Separate "true" efficiency losses from auxiliary consumption as far as the data allows.
- Propose and fit a model that predicts auxiliary loads and efficiency losses.
Part of your task will be to help define innovative ways of approaching this problem, with support from our team
Your background: - Background in energy systems, control, electrical engineering, applied mathematics, physics, or similar.
- Solid background in data analysis and interest in battery system modeling.
- Strong analytical skills and an interest in data visualization.
- Curious about battery technology and its role in the power system.
The project can be carried out by one or two students in collaboration.
Location
Our beautiful office is located in the heart of Södermalm just a short walk from Slussen subway station. We prefer in-office collaboration for this matter.
