Dashboard
The Monitoring Dashboard visualizes the power flow results of the time series simulations.
The inputs to the simulation are smart meter based time series measurements of demand and generation and voltage measurement at the slack bus.
The automatic data import can be set up in Monitoring Updates.
Simulation Log
The simulation log provides a detailed log of the power flow simulation at each time step.
Informations, marked as , indicate a possible problem, whereas warnings, marked as
, indicate that the simulation at certain time steps could not be finished as expected.Click on a log category to see more details.
Grid Viewer
The Grid Viewer shows all elements and their worst state during the selected time range. In case of violations of the Operational Limits, the respective element will be colored red. In case of warnings, the respective element will be colored yellow.
Dashboard
The Dashboard can be customized to show the desired information related to the simulation results. By default the Dashboard shows the following information:
- Total Active Power
- Loading (Lines) as quantiles
- Voltages (Buses) as quantiles
A custom Dashboard can be created by clicking in the top left corner. After specifying the data to be shown click on to save the custom dashboard. All saved Dashboards can be accessed through the dropdown list.
The following elements can be added to the Dashboard:
Chart
Charts are plots of the measured or simulated data. The x-axis represents the physical quantity of the data and the y-axis is the time step. An extensive list of plottable values is available, such as:
- Bus voltage
- Line loading
- Transformer loading
Text
Text can be used as descriptive element in the Dashboard. The text editor supports different formatting options.
Alerts
Alerts reveals a list of warnings and violations of the Operational Limits of the electrical components in the grid for the defined Timeline.
Losses
Summarizes the overall grid losses per voltage level in a tabular format.
Active power match
The Active power match plots the Slack Bus Measurement, Smart Meter Load, Smart Meter Generation and calculated grid losses in the same chart. This is useful to check if the Total Load (including losses) in the grid matches the power measured at the Slack Bus. 
TIP
A power mismatch, where the Total Load (including losses) lies below the Slack Bus Measurement can be an indicator for any of the following:
- incomplete Smart Meter Rollout in the grid
- Power theft
- incorrect mapping of the Smart Meter to the connection point in the grid
- incorrect Slack Bus or Smar Meter measurements
A power mismatch, where the Total Load (including losses) lies above the Slack Bus Measruement can be an indicator for:
- incorrect mapping of the Smart Meter to the connection point in the grid
- incorrect Slack Bus or Smar Meter measurements

Interaction with Charts
Aggregation
Data in the charts can be plotted and aggregated in several ways.
For aggregation there are the following options:
- 1: no aggregation of the data.
- Σ: data points are summed up at each time step.
- X̄: data points are averaged at each time step.
INFO
Some plots only make sense if no aggregation option is selected.
Visualization
The data can be visualized in different plots or tables, depending on the need. The following options are available:
- Quantiles: Shows the quantiles of the data points in different shades of blue. The Median, plotted as black line, is the value that separates the upper from the lower half of the data points. The dark blue band represents the 25%-75% range of the data points. 25% of the data points lie above and below this range. The light blue band represents the maximum and minimum range of all data points.
- Line Plot: Plots the data of each element individually, differentiated by color. Hovering over a line reveals the ID of that element. If too many elements are present in the grid, only a subset is plotted by default and a warning will be shown represented by . The limit can be ignored by clicking on .
- Histogram: Plots the distribution of the underlying data.
- Box-Whisker Plot: Plots the range of the underlying data per element over the specified time range through their quantiles.
- Duration Chart: The x-axis shows the percentage of the total time range and the y-axis the value of the variable. The chart shows for what percentage of the overall specified time range the variable is above or below a certain value.
- Table: Shows the minimum, maximum, average and relative average (average/maximum) of the values over the specified time range for the underlying data.
Clicking on an element in the Grid Viewer while pressing Ctrl adds that element to the selection and the data in the chart is filtered to the data of the selected element. Multiple elements can be selected together. The data in the chart can also be locked by clicking on . In that case the filter will have no effect on the data visualized.
Open the chart in full screen by clicking on .
Downloading
The data from a chart can be downloaded by clicking on .
Timeline
The Timeline at the bottom of the page is used to control the time range of the data to be shown. The y-axis displays the number of warnings and violations and the x-axis shows the date and time.
The time range can be manipulated in several ways:
- Clicking into the timeline and dragging the mouse pointer from the start date to the end date.
- Clicking the , , , shows the specified range, for example one week.
- Going backwards or forward in time in steps of days, weeks, months or years by clicking on the respective buttons or .
- Selecting the from and to dates in the bottom right.
Report
The entire Dashboard can be printed or saved as a Report by clicking on at the top right.
Load Situations
Load situations are static load scenarios that can be created from the time series measurements. A load situation replaces the static load and generation in the grid when running Static Calculations.
Clicking on opens the Load situations settings.
The following load situations can be created:
- Selected point in time: The load situation is created from a specific point in time that can be specified by providing the date and time.
- Overall maximum residual net load: automatically selects the point in time between the specified interval start and interval end where the residual load [1] in the grid is highest.
- Overall minimum residual net load: automatically selects the point in time between the specified interval start and interval end where the residual load in the grid is lowest.
- Per-bus maximum residual loads: automatically selects the higest residual load at each bus between the specified interval start and interval end. This represents a worst case load situation, since it assumes that the maximum residual loads per bus occur simultaneously.
- Per-bus minimum residual loads: automatically selects the lowest residual load at each bus between the specified interval start and interval end. This represents a best case load situation, since it assumes that the minimum residual loads per bus occur simultaneously.
Deletion of existing loads/generators
This setting defines if all or only a part of the existing loads and generators in the grid are replaced when creating the load situation.
- Remove all: All loads and generators of the grid are deleted, even if they are not considered in the load situation (e.g. because they don't have a time series behavior). Choose this option if the data from the load situation shall replace all existing static load and generation.
- Remove considered devices only: Only devices that were considered in the creation of the load situation are actually removed by the load sitation. Other devices / connection requests that were not considered in the load situation are not deleted.
INFO
Load situations can be applied in all Static Calculation tools:
Operational Limits
Clicking on opens the settings to change the operational limits of the electrical components. The alerts and coloring are calculated based on these settings.
Residual load is the difference between power demand and power produced from non-dispatchable generators. ↩︎
