Seamless interaction with Online Monitoring*
The Congestion Management App is part of our package of grid operation apps and is natively connected to the *Online Monitoring app. In Online Monitoring, grids that are at risk of getting congested are detected automatically based on minute-by-minute state estimation and passed on to the Congestion Management App. You can also move such grids from one app to the other manually.
Automatic calculation of power consumption
In the Congestion Management App, the power consumption, to which a manageable consumption asset is to be throttled, is calculated automatically. The curtailment is executed in a non-discriminatory manner and only to the extent that is required to prevent the grid congestion. Based on the minute-by-minute state estimation, the control commands are dynamically adapted. If the grid situation eases, the consumption limits are gradually lifted.
In the detailed view, you can see the reduced power per manageable asset.
Transmission of control commands
The control commands for curtailment to the calculated power consumption are sent to the individual consumption appliances via the responsible metering point operator. You can view in detail which assets are being controlled at the current time. The duration of the curtailment measures is limited to the necessary extent to alleviate the grid congestion risks.
Topological live view of the control process
With the live topological view, you can keep track of ongoing control interventions. The visualisation displays all available controllable assets along with their current status: actively controlled, not included at the moment, control command sent but not successfully executed.
For each asset, details such as device type, ID, nominal power, and control stages are available. Affected grid areas, such as supplying transformers or cables, are also visually highlighted. To examine concurrently running control interventions individually, you can analyze each grid section separately. You can also toggle the visibility of both consumers and bottleneck areas as needed.
Documentation of control measures
All grid areas where grid-oriented control measures have been applied are documented and can be exported and downloaded if necessary. In addition, the app includes an event log that records all relevant system messages during the control event – from info messages to warnings and errors. For each event, the timestamp, affected grid area, and the response triggered by the app are displayed, allowing to quickly detect any anomalies or exceptions in the automated control process. This way, you can always share this information with other parties in case you’re required to justify throttling the power consumption within a specific grid area.
Secure grid operation
The Congestion Management enables you to quickly and reliably address overloads at the low-voltage levels and ensure the safe operation of your grids.
Time for grid expansion
The introduction of intelligent control of the assets in the grid helps you to gain more time for grid reinforcement and expansion measures by reducing the risk of grid congestion.
Grid flexibility
In combination with the Online Monitoring App, the Congestion Management App allows you to successfully introduce grid-side flexibility at a low-voltage level.
