Reference to Test Case | TC18 Evaluation of various service definitions and activation patterns |
Title of Test | Evaluation of system services and activation patterns after functional disruption in the local grid |
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 (graphical) | |
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 |
