How can I get losses in each lines of the network. what command should be used. Can I get the power entering and leaving at all lines with some code? If yes what is code to get it.

Thank you so much. I am modeling a load at bus 2 as per your sugestion. Please look at the load model below if i am writing it correctly or not. And what is the diference between Vminpu Vlowpu Vmaxpu? How should I select value of these parameters? new load.load2, bus1=2, kv=12.66, kw=100, kvar=60, model=4, CVRwatts=0.72, CVAvars=2.96, Vminpu=0.0085, Vmaxpu=1.9, Vlowpu=0,

Hi all! How can i model the load where power is varying according to voltage (That is power is varying as the voltage is changing). Actually I want to model it as per Pload=Pnominal(|V|)^pr and Qload=Qnominal(|V|)^qr where Pload, Qload = voItage dependent real and reactive power load. Pnominal, Qnominal= real and reactive load at nominal voItage. V= voItage magnitude pr, qr= real and reactive power load co-efficients for residential load model. I have pr= 0.72 and qr=2.96 for my case.

Za, Zb, Zc are phase impedance in pu of a unbalanced line; These are not the sequence impedance. Actually I have got this data from a reference paper X. Chen, W. Wu, and B. Zhang, “Robust capacity assessment of distributed generation in unbalanced distribution networks incorporating anm techniques,” IEEE Transactions on Sustainable Energy, vol. 9, no. 2, pp. 651–663, 2018. where the author have shared his data on drive; https://drive.google.com/file/d/0BzBNHekT7PzcR1V4eG1NZC1EOVU/view?usp=sharing....

Thanks for your timely guidance. Actually I just taken the branch as modeled in balanced system, while changing the Load at at each node to be unbalanced. can you please suggest how can i model the line which is having following details: The impedance of branches ij. Line FromtoTo Bus i Bus j Za(pu) Zb(pu) Zc(pu) Line1to2 1 2 0.0935 + 0.0477i 0.0933 + 0.0475i 0.0931 + 0.0474i Line2to3 2 3 0.5003 + 0.2548i 0.4989 + 0.2541i 0.4979 + 0.2536i

Thank you sir for your guidance. I will consider these changes in my work. Actually I am trying to get the loadability (MaxLoadLimit) of the system. For this I have to increase the load at each bus, and this load increase will change (reduce) the voltage of system nodes. To consider the single load model (Model 1) I wanted to give the Vminpu such that increasing the load on each bus system load model does not changes, that was the logic behind giving the Vminpu as minimum as possible. Put some l...

Now I have anew question. I am running a script file for load flow . Defining the each and every load connected to circuit as (for example load at node 2) new load.load2_1 bus1=2.1 Phases=3 Conn=Wye model=1 kv=12.66, kw=45.3836 kvar=27.2009 Vminpu=0.95 Vmaxpu=1.5 Vlowpu=0.02 gives me the result of 209.40 kW. changing the Vminpu=0.5 or 0.8 gives the result of 238.49 kW. Now I have removed the last three phrases of load model by defining the load model as new load.load2_1 bus1=2.1 Phases=3 Conn=Wye...
