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.
