With MATPOWER 7 and earlier, unfortunately, there isn’t a really clean way to accomplish this. The way that comes to mind is to represent each load with a “fake” generator, and then add some user-defined nonlinear constraints (as described in Section 7.1.2 in the User’s Manual) that define the output of those “generators” as a function of the bus voltage.
In the development version of MATPOWER based on MP-Element<https://github.com/MATPOWER/mp-element/>, this will be easy to implement via a definition of a few new classes. But, the mechanisms for doing so are not yet completed and documented … … but it’s coming … Ray On Jan 10, 2022, at 4:22 AM, Arpit Srivastava M.Tech., Electrical Engineering, IIT(BHU) <[email protected]<mailto:[email protected]>> wrote: Hello Matpower Users, Please let me know How to run load flow with voltage dependent load models. In my case each bus load have to be modeled as: Pload= Pl*(V)^pr Qload= Ql*(V)^qr where Pload, Qload = voItage dependent real and reactive power load. Pl, Ql= real and reactive load at nominal voItage. V= voItage magnitude pr, qr= real and reactive power load co-efficients for residential load model. Assume pr= 0.72 and qr=2.96 for the present case.
