Hi @Thuong,
Thanks for sharing your comments and the screenshot from your Powergui Load Flow run. I reviewed the image and checked the MathWorks documentation for the Load Flow Analyzer in Simscape Electrical (Specialized Power Systems).
From what I can see, your network is being parsed correctly — all the synchronous machines (M1, M2) and RLC loads appear in the Load Flow table with proper voltage bases and power values. However, the wind generator is not listed because the Load Flow Analyzer only includes specific supported block types for steady-state calculations.
At present, the tool recognizes blocks such as:Synchronous Machine,Simplified Synchronous Machine,Asynchronous Machine (if directly placed in the model and its Load Flow tab parameters are defined),Three-Phase RLC Loads and Sources.
Converter-based or subsystem wind-turbine models — for example DFIG, PMSG, or full-converter wind turbines — are not yet supported for automatic load-flow initialization. Because these generators include power-electronic converters and controls, Powergui treats them as dynamic elements rather than steady-state sources.
If you need the wind generator to participate in load-flow results, a couple of workarounds can help:
1. Expose the internal Asynchronous or Synchronous Machine block (if your wind model uses one) and fill in its Load Flow tab with the rated P and Q values.
2. Represent the wind generator as an equivalent PQ source connected to the same bus for initialization purposes, then switch back to the detailed model for dynamic simulation.
Everything else in your screenshot looks correctly configured — the buses, base voltages, and synchronous generators are fine. It’s just that the Load Flow tool doesn’t yet compute the converter-based wind generator’s steady-state point.
Hope this clarifies why the block isn’t appearing in your results.
