01 / Context
Overview
This PSCAD study models a droop-based grid-forming three-phase voltage-source inverter and compares grid-following and grid-forming control under weak-grid conditions.
It connects converter modeling with power-system questions: how the control structure interacts with the surrounding grid, and how the inverter responds when grid strength is reduced.
My work
- Modeled a droop-based grid-forming voltage-source inverter in PSCAD.
- Simulated and compared grid-following and grid-forming control for weak-grid conditions.
02 / Approach
Methods & diagrams
Grid-following case
The grid-following model provides one side of the control comparison.
Droop-based grid-forming case
The grid-forming implementation supplies the contrasting converter-control structure documented in the CV.
Weak-grid comparison
The two approaches are compared in PSCAD under reduced grid strength. Numerical settings and exported results can be added when the source cases are available.
Findings
- The modeled control comparison provides a foundation for further converter-grid interaction studies.
Scope & limitations
This is a simulation study of grid-following and droop-based grid-forming control under weak-grid conditions. Hardware validation and grid-code compliance testing are outside the documented scope.
The cover illustrates the topic; it is not a PSCAD model or a measured response.
