I didn't have time to look at the paper, but my suggestion doesn't necessarily assume a lossless line, just that the flow in the line (and the losses in it) are specified as inputs and not dependent on the solution. This may be good enough depending on your application.
If you are looking at modifications to the Newton power flow, you'd find that code in newtonpf.m. -- Ray Zimmerman Senior Research Associate 211 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jan 11, 2011, at 9:41 PM, jeramy mendoza wrote: That assumes that the link is lossless right? I saw a paper which modifies the newton-rhapson iteration to include HVDC losses.My problem is how to access in Matpower the bus voltages in each iteration,& consequently to use it to determine the voltages in the rectifier & inverter bus. I'm ok with the concepts, my problem is how to implement it in Matpower. The paper is attached herewith. Thanks Mr. Zimmerman. .
