MMC non linear equations solve

I need to find the magnitude of AC voltages and its angle and values of dc voltages so there are total 18 variables and i have total 18 current non-linear equations and no parameters are given so what kind of solver should i use ??

Hi @MAHEEP BHATT

You can use these solvers:

• fsolve is a robust function for solving systems of nonlinear equations. It requires an initial guess for the variables and attempts to find a solution that zeroes the system. Refer to this link: https://www.mathworks.com/help/optim/ug/fsolve.html
• lsqnonlin: Useful if you can reformulate your problem as a least-squares problem. Refer to this link: https://www.mathworks.com/help/optim/ug/lsqnonlin.html

I hope it will help.
