With retoflow, you can create a digital image of your grid - not as a one-off snapshot, but as a continuously updated grid model: - Regular grid data updates from GIS and ERP - Synchronization of connection requests from the connection portal - Connection of metering equipment for grid operation This means that you always make all decisions based on the latest data - from grid operation and connection planning to target grid planning. ![Grid Operations - § 14a EnWG](https://www.retoflow.de/hubfs/Stromnetzplanung%20-%20Netzbetriebsbild-2.png) ## Grid Operations Efficiently implementing Section 14a of the German Energy Industry Act (EnWG): retoflow integrates grid planning and grid operations through a shared, computable grid model serving as a digital twin.

[learn more](https://www.retoflow.de/en/target-grid-planning?hsLang=en) **GRID MODELING**   ## **A uniform database at all voltage levels** With retoflow, you can create a uniform digital image of your entire grid area. Thanks to integrated modeling across all voltage levels, you can keep a close eye on the voltage band and avoid duplicate data storage. With the retoflow grid filter, you can simply select the exact grid area you want to view. retoflow automatically aggregates underlying grid areas and dynamically creates the necessary equivalent loads. ![Stromnetzplanung\_Netzmodellierung-3](https://www.retoflow.de/hubfs/Monitore/Stromnetzplanung_Netzmodellierung-3.png) ![Allgemein\_Netzberechnung-1](https://www.retoflow.de/hubfs/Monitore/Allgemein_Netzberechnung-1.png) **GRID ANALYSIS**   ## All the possibilities of grid analysis retoflow offers all important grid calculation methods for grid planning and operation applications: - Load flow simulation (balanced / unbalanced) - Short-circuit calculation in accordance with IEC 60909 or VDE 0102 - N-1 failure calculation with resupply simulation - Reliability calculation (ASIDI / ASIFI) - State estimation based on measurement data (state estimation) **GRID SIMULATION**   ## **Flexible grid simulation for any data situation** The correct mapping of simultaneities is the greatest challenge in the simulation of distribution grids. This is why retoflow automatically creates the relevant worst-case scenarios, individually for each supply area and each outgoing circuit. Depending on the data situation, this can be time series-based from SLP and RLM profiles or performance-based on the basis of simultaneity functions. ![Allgemein\_Zeitreihensimulation](https://www.retoflow.de/hubfs/Monitore/Allgemein_Zeitreihensimulation.png) ![Allgemein\_Netztransparenz-1](https://www.retoflow.de/hubfs/Monitore/Allgemein_Netztransparenz-1.png) **GRID TRANSPARENCY**   ## **Transparency across the entire grid area** Thanks to innovative algorithms and efficient data management, the entire grid area can be stored and calculated in one model in retoflow. This gives you a quick and intuitive overview of the current capacity utilization situation in the entire grid area. With the retoflow scenario editor, you can also simulate future grid conditions and thus identify bottlenecks in the grid at an early stage. ## Frequently asked questions I don't yet have a digital image of my low and/or medium-voltage grid that is capable of computing. How does the introduction to retoflow work? We create a computable grid model for you directly from the existing source systems.  In most cases, this is the geographic information system (GIS) for the network topology and the billing system for the dimensioning of loads and generators. Other data sources such as the asset system, grid connection portal and metering database can also be linked to the digital twin of retoflow, depending on the application. I already use a classic grid calculation program. Can I also link this with retoflow? Yes, it is possible to transfer grid models from programs such as PowerFactory, SINCAL or NEPLAN. However, you will only benefit from all the advantages of the digital twin if changes in the source systems can be transferred automatically. In most cases, a direct connection to the source systems is the best way to do this. We will be happy to analyze your current situation with you and evaluate the best solution. Are there minimum requirements for data quality in the source systems? On the contrary: retoflow helps you to gain an overview of data gaps and eliminate inconsistencies. Statistics on data quality provide an overall view of data quality and data checks provide specific indications of elements with incorrect modeling. This allows you to target the elimination of data errors in the source systems. **LIVE DEMO** ## experience the retoflow platform Take the opportunity to arrange an appointment with our experts [Live-Demo](https://www.retoflow.de/en/demo?hsLang=en) [![retoflow](https://www.retoflow.de/hs-fs/hubfs/v-logo-schwarz-2.png?width=1584&height=330&name=v-logo-schwarz-2.png "retoflow")](https://www.retoflow.de?hsLang=en) --- [linkedin-in icon](https://www.linkedin.com/company/retoflow/) ### Links Lösungen Kontakt  Karriere Kontakt Impressum ### Kontakt retoflow GmbH Universitätsplatz 10 34127 Kassel [![retoflow](https://www.retoflow.de/hs-fs/hubfs/v-logo-schwarz-2.png?width=1584&height=330&name=v-logo-schwarz-2.png "retoflow")](https://www.retoflow.de?hsLang=en) # Follow us [linkedin-in icon](https://www.linkedin.com/company/retoflow) [Folgen Sie uns auf Facebook](https://www.youtube.com/@retoflow) # Legal [Imprint](https://www.retoflow.de/en/imprint?hsLang=en) [Data protection](https://www.retoflow.de/datenschutz?hsLang=en) **© 2024– retoflow GmbH**
