No FCU dispatch data loaded. Select an FCU asset from the Network Analysis page. If no FCU assets appear there, verify that EMS result export is enabled in the FCU configuration for this scenario.
Flexibility Asset Operation & Market Participation
This page characterises the operational behaviour of Battery Energy Storage Systems (BESS) operating under market-coupled Energy Management System (EMS) control. It presents the economic dimension — market participation and revenue generation — alongside the physical dimension: power flows and SoC trajectories. The analysis is descriptive and neutral; no 'optimal' operation is implied without a defined reference or objective function.
Key questions
→
How does the BESS respond to day-ahead and intraday price signals?
→
How are available SoC cycles distributed over the simulation period?
→
What trade-offs exist between market revenue and battery utilization depth?
→
Are there periods of high operational intensity or inactivity?
→
What operational regime (arbitrage, peak shaving, FCR) dominates the strategy?
Usage note
Navigate here from the Network Analysis page by selecting an FCU asset. Results depend on the specific EMS variant and configuration used in the scenario.
Methodology
FCU = Flex Control Unit (COSIM EMS simulator). Market signals (DAA, IDA, spot) are inputs to the EMS optimisation; dispatch is determined by the configured EMS logic, not post-hoc fitting.
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.
