questions on mpoption

2015-09-20 Thread rainy chung
hi everyone,

when using mpoption to define the power flow running manner, what's the
difference between setting mpopt=mpoption(mpopt,'pf.enforce_q_lims',1) and
without specifying it. Thanks!

I made an experiment, it seemed the VAR limits with and without specifying
this are the same.

Thanks Sir, I will try that. By the way, I am wondering whether you know
how to add new varaibles z using direct specification method? Many thanks!

Best Regards!

 You can modify the test case so that the bounds are very tight on the
 variables you would like to keep constant.

 Cheers,
