The “Peak billing yield losses (active power limitation)” report breaks down whether a system has been regulated. In contrast to the (relative) version, the (DVM and NSM) version can distinguish who has controlled. Whether this is possible depends on whether the data logger/park controller sends the control signals in a differentiated manner.
Prerequisites for report generation
Irradiation data at facility level
Irradiation at facility level is a prerequisite.
There are two options for this:
- If several sensors are available: Calculations of the average irradiation value.
- If only one sensor is available: Direct reading mapping.
Note: If no irradiation sensors are available, contact your Customer Success Manager to acquire satellite data if necessary..
Calculation
During the calculation, the average irradiation from several sensors is calculated.
- Navigate within the digital twin to your facility and then to Calculations.
- Click on Create.
- Enter irradiation under Measured values.
- Click on + Add and add the corresponding sensors.
- Set the calculation to AVERAGE.
- Then click on save.
Direct reading mapping.
If only one sensor is available, it can be directly mapped as the measurement value.
The following three signals can be captured:
- Active power limitation (Trading) (active power limitation through direct marketing)
- Active power limitation (Grit Operator) (active power limitation through grid security management)
- Active power limitation (Relative) (result from DVM and NSM - always the lower value)
- If only an unknown value is sent, this (relative) value must be assigned.
- If DVM and NSM are available, but no relative value, this must be activated in formulas. Jump to details
- Navigate within the digital twin to your facility and then to the Reading Mappings.
- The measured value irradiation must be mapped
- Click on “Add”.
- Select the facility's data logger as the source.
- Search for the corresponding reading under Data stream:
In this example, it would be "POWER_PLANT_CONTROLLER/PPC_P_SET_GRITOP_REL" for the grid operator. - Unter Reading Type select the corresponding reading:
In this case, active power limitation (grid operator) - Check whether a Correction (Divisor) is required:
- If values between 0-100 are sent, they must be divided by 100, as the system expects values between 0-1.
- Click on Save.
- If DVM and NSM are available, but no relative value, it must be activated in formulas.
Activating the formula for calculating the relative value
- Navigate to Formulas.
- Click on “Create”.
- Select the formula “Site: Calculation of a Continuous Signal for Active Power Limitation (Grid Operator) [5m]”.
- Save the formula.
Checking the correct setup
- Navigate to Monitoring.
- Select the facility.
- To check whether the following values exist, open a new column for:
- (Current) Active power limitation grid operator
- (Current) Active power limitation Relative
- Current) Irradiation
Click on the 
symbol to show and hide graphs.
- Active power limitation Relative
- Irradiation data
Note: If the relative value is calculated using a formula, it may take a few minutes for the values to be visible.
If irradiation has been added by calculation, it may take a few minutes before the values are visible.
- You can now use the data to see when the facility is regulated.
- You can now use the Yield losses report.
Creation of the “Peak billing for loss of income” report
- Navigate to the “Reports” tab.
- Select the report “Peak billing revenue shortfalls (relative)” or - if differentiated - “DVM and NSM”.
- Select the corresponding attachment and the desired time period.
- Enter the recipient (user/email address).
Note: As the report is output as an Excel file, saving as a PDF is not recommended.
- If irradiation was added by calculation, it is only displayed from the time of activation.
- If a retroactive calculation is required, this must be recalculated under Calculations.
Additional information:
- The report was implemented in accordance with the guidelines for peak billing.
- If no reference day is found in the last 30 days on which no regulation has taken place, a default value of 0.9 is used as the performance ratio.
