Re: Effect of loads in IEEE 39 bus system
Hi Shri, Sorry for not stating my problem clearly. I need to implement ZIP load model in matpower to evaluate it's effect, instead of constant power load in runcpf. P = P0[ a1 (v/v0)2 + a2(v/v0) + a3 ] Vo is the rated voltage of the device, and Po and Qo is the power consumed at rated voltage. This is the equation I need to implement. I tried understanding the runcpf code, But I couldn't make out where to make those changes. Is it possible to tell where to make those changes or the name of the matlab file used for this?

But now I am stuck as to how to implement it in matpower. Can anyone please give me some guidelines as to how I should proceed so to get it implemented. Your help will be greatly appreciated, its for my graduate research. Thanking you and With Regards, Arun Nair

HI Shri, Thanks for the reply. It's good to know that it's possible to do it using Matpower. I will try to model loads.

MATPOWER models loads as constant real and reactive power injections. So, you'll have to implement all the load models.
