BESS Operational Regime Characterisation
Characterises the operational 'fingerprint' of a BESS unit: which strategies dominate, when dispatch occurs during the week, and at what state of charge dispatch events are triggered. The radar chart condenses five dimensions into a single visual signature.
Key questions
→
Does this unit primarily arbitrage price spreads or shave peaks?
→
Is dispatch concentrated in specific hours or days?
→
At what SoC does the battery typically begin charging/discharging?
→
How price-responsive is the EMS strategy?

Methodology
Radar axes are normalised [0-1]: higher = more intense in that dimension. DoW x hour heatmap uses hourly-averaged absolute power. SoC onset histogram samples transitions from idle to active dispatch.
Research-as-a-Service platform for studying the interaction between flexible energy assets, electricity markets, and distribution-grid operation.
Research & Development
The COSIM Cockpit platform is developed within the collaborative research and development activities of the Institute for High Voltage Equipment and Grids, Digitalization and Energy Economics (IAEW) — Active Energy Distribution Grids group — at RWTH Aachen University and the Fraunhofer FIT research team Digitale Energie. The work combines academic expertise in active distribution networks, grid operation and planning, and flexibility integration with applied digital-energy system development and engineering-oriented analytical tooling.

The COSIM Cockpit is a research and engineering platform developed at IAEW RWTH Aachen University and Fraunhofer FIT. Results are based on simulation models, modelling assumptions, and scenario-specific input data. Real-world system behaviour may differ from simulated outcomes. Analyses do not constitute operational guarantees or binding engineering assessments.
No warranty is provided regarding completeness, correctness, or fitness for a specific operational purpose. Users are responsible for independently validating conclusions before applying them to real-world decisions.
Research use only: This platform is designed exclusively for research and academic analysis. Results must not be used as the sole basis for investment, operational, or regulatory decisions without independent engineering validation.
Market data: Electricity price time series used in simulations (DAA/IDA from ENTSO-E Transparency Platform and EPEX Spot) are subject to the respective platform terms of use. Data are used solely for non-commercial academic research. Redistribution or commercial reuse requires separate authorisation from the original data provider.
Confidentiality: Simulation scenarios, configuration files, and result data may contain confidential project-specific information. Exported results and reports must not be shared beyond the intended audience without prior authorisation.
