Diagnostics tests
The A- and D-series charge/discharge curves are diagnostic test profiles designed to validate the power control behavior, dynamic response, and sign-handling of flexible energy assets. They are not intended to optimize energy or revenue, but to prove correct behavior under controlled, repeatable conditions.
Together, these tests answer three core questions:
- Can the asset follow a requested power setpoint accurately?
- How quickly and smoothly does it respond to changes?
- Does it behave symmetrically and safely across charge, discharge, and idle states?
Supported Devices
| Device Type | Variants | Supported |
|---|---|---|
| Solar Inverters | All | ❌ |
| Storage Devices | ✅ | |
| EV Chargers | ❌ |
How to configure the diagnostic test
- Go to 'External data sources', followed by 'External Signal'
- Look for the Eniris or SmartgridOne-logo in the list of providers and click on it.
- Select 'Diagnostic tests'
- Provide these two inputs:
Select the test curve to perform: Select one of the tests from the dropdown menu.Select the start time of the test (HH:MM) in the UTC timezone: The test will start on this timestamp. Important, the timestamp must be given in the UTC timezone. If you are not sure what this means, go to https://time.is/UTC to get the UTC time, and add 5 minutes. The test will automatically start in 5 minutes.Maximum charge and discharge power in kW: The tests maximum charge and discharge will be scaled towards this value. In the images below, the test is scaled to 100 kW.
Test types
A-curves
A-curves are short tests to do an initial (and fast) test of the system performance.
D-curve
The D-curve is implemented by design of the Swiss TSO (Swissgrid) to mimic a prequalification test.
