Test Specification 18.01
Test Rationale
Aim is to evaluate system services and connected activation patterns of an aggregator platform during and/or after a functional disruption in the near location (e.g., Fault Ride Through, blackstart assistance, virtual inertia provision)
Specific Test System
Target measures
The test scenarios serve the validation of continuous service provision under various disruptions and system settings.
Input and output parameters
Control signal before and after the disruption as an input. Active power as an output.
Test Design
30 minute long simulation period during which a disruption is introduced that breaks the connection of communication and/or electricity from aggregator/public grid.
Initial system state
Initially the system service is operating normally and the grid is functioning without disruptions.
Evolution of system state and test signals
A disruption is introduced. Communication and/or grid connection is momentarily lost. System(s) providing the flexibility service is then evaluated to see if nornal operation can be established again.
Other parameters
communication latency, communication signal, voltage and current observed from the DER(s)
Temporal resolution
1 second resolution
Source of uncertainty
Only certain amount of different kind of disruptions can be tested for. In other words, everything cannot be tested.
Suspension criteria / Stopping criteria
30 minutes or permanent loss of communication and/or grid connection
