What is the best method to model or use the built-in model for a three-phase voltage regulator in MATLAB Simulink, specifically for the IEEE 34 distribution network, in a way that works properly with load flow analysis from the Powergui?

Hi Asi,

To model a three-phase voltage regulator in MATLAB Simulink for the IEEE 34 distribution network and with load flow analysis using Powergui, you can refer to the following resources:

• For a Three-Phase Voltage Regulator model  with variable output voltage capabilities, by varying the delay of the thyristors in a star-connected load setup, you can refer to the link below: https://www.mathworks.com/matlabcentral/fileexchange/54690-three-phase-voltage-regulator
• For discrete modelling of the IEEE 34 Bus Distribution System, complete with voltage regulators and ZIP loads, you can refer to this comprehensive model. Top of FormBottom of Form https://www.mathworks.com/matlabcentral/fileexchange/123220-ieee-34-bus-distribution-feeder-discrete-simulink-model
• For conducting load flow analysis, you can refer to the detailed example of a 5-bus network using Powergui. https://www.mathworks.com/help/sps/ug/initializing-a-5-bus-network-with-the-load-flow-tool-of-powergui.html

By leveraging these models, you can effectively simulate a three-phase voltage regulator and perform load flow analysis within the IEEE 34 distribution network in Simulink.

@MULI , I used the second link for IEEE 34 , but when i applied the load flow analysis is stuck at the bus where the voltage regulator is connected.

Do you have any idea to solve this ?
