Re: HVDC and SVC

[Carlos E Murillo-Sanchez]

To clarify a little further on Ray's advice: An SVC can be approximated by a generator under voltage control that can sink QMIN or source QMAX MVArs, but this would be accurate for an SVC with a slope of infinity (i.e., constant voltage).  If you want to approximate the behavior of an SVC in the linear operational region, then, in an optimal power flow (but not in a simple power flow) you can relate the voltage of the controlling bus to the reactive output of the SVC using the generalized linear constraints feature.

And an SVC can be modeled as a generator with PMIN and PMAX equal to 0.    Ray On Nov 14, 2018, at 5:43 AM, in...@gotalk.net.au wrote: Dear Ray   Does MATPOWER support any form of HVDC or SVC?   Kind Regards   Alberto Sarnari
