Includes tests required as per the "Dynamic studies" section of the AusNet Services | System Study Requirements 1.5 - 5 MW| May 2023

Configuration

To use this template:

Configure your global and scenario variables by using gridmo's Model setup template.
Download this template using the download button above and load the template into the gridmo web-app.
Transfer your general tab data, global variables and scenario variables across using the 'Import' buttons in the gridmo web-app.

This template currently only includes the tests listed under the section "Dynamic studies" and is configured for asynchronous generating systems.
PSCAD™ The template enables the PSCAD™ Nodes by default, assuming that PSCAD™ studies are required because "system strength limitations...are identified".
Section (i) & (ii) Flat runs:
- We have assumed that a 30 second simulation is sufficiently long to demonstrate flat run stability.
Section (vi) Voltage disturbances:
- Infinite inertia is used for these tests, which may not be applicable for grid-forming inverter systems.
- The voltage waveforms applies have been configured such that the time spent within that range includes any time spent in the more onerous ranges.
Section (vii) Frequency variations:
- Tests are conducted using a playback generator with infinite inertia.
- Network frequency dependency has been turned off.

15 April 2024 (v1.4.12):
- Updated to align with newest template Sticky Note format.
- Slight changes to the Start Nodes in the template to make Analysis Node outputs easier to read.
5 December 2023 (v1.4.6)
- First version released.
