Hi friends doing my M.E project on reconfiguration of radial distribution network for that first step is to find load flow in radial distribution network can any body help me to do with the matlab coding for this please help

@arunchary • 11 Sep, 2013
can you please share the related paper such that we can provide a solution............

load flow now ok have to start with branch and bound technique

@shruti21 • 16 Sep, 2013
hello boss. doing my project on the topic reconfiguration of distribution network for loss minimization and facing the same problem of radial load flow. i have gone through a few of radial load flow papers based on forward backward sweep. coding part is problematic. i really need help! please help

@maraitamilan • 16 Sep, 2013
hi Shruti21 using which technique going to reconfigure.... and btw i got load flow for radial system

@shruti21 • 16 Sep, 2013
using GA. u got the load flow code ?

@maraitamilan • 16 Sep, 2013
u are using only one objective or multiobjective????..... ya got the code

@arunchary • 16 Sep, 2013
hi guys please share the following code where u getting issue ok such that ill go through once and ill try to solve ok...........

@shruti21 • 16 Sep, 2013
hi sir..share ur email id ,so that i can mail u the code

@Abhishek Rawal • 16 Sep, 2013
@shruti21 Why not share your Matlab code here itself ?

Many CEans will indirectly get help from your code too.

hello sir i have a same problem, my project is reconfiguration network fo real loss reduction to increase the reliability network, may anyone may help me with the matlab code, it's starting to depressed me...

@Chaitali Sumita • 11 Feb, 2014
Hi friends....

I've solved different papers for load flow in radial distribution system and one paper for mesh network.

So I can help you for load flow..

But i need some help in reconfiguration. How can i approach for reconfiguration????

Waiting for your replies.

First u've to do load flow analysis for radial distribution system.

after this u can get the idea how to integrate Distributed generation into radial distribution system and how to do reconfiguration.

so choose a good paper and start writing program for load flow of radial dist. system.

counting load flow???

do you mean number of iterations???

if so, try to implement the load flow for radial as well as mesh networks for 33 bus system. Later u can remove the loops one by one in mesh load flow program to count number of iterations...

for IEEE 33 bus system, You'll get less number of iterations for mesh network (with 5 loops) than radial network.

@Raviteja16 • 21 May, 2014

for finding line charging current, you can take the voltages at sending and receiving end nodes....

In his point of view, suppose line 2 is in between 2nd and 3rd buses (nodes).

Ic2=(0.5*Y2*V2)+(0.5*Y2*V3).

But we can't assume that the difference between sending end node and receiving end node is 1. for ex, Some lines (say 9) may exist between 2nd and 23rd nodes.

in this case, according to his formula;

Ic9=(0.5*Y9*V2)+(0.5*Y9*V23).

Use sending end node and receiving end node voltages for finding line charging currents instead of using Vb and Vb+1.

Moreover, for IEEE 33 and 69 bus distribution systems, line charging admittance is zero.

So u can avoid it...

I didn't perform load flow for balanced radial distribution system with line charging admittance. If you have the data with line charging admittance, tell me the title of that paper. i too will solve it.

He has given laterals, sub laterals, main lines, etc......

No need to consider all those things while writing program for balanced radial distribution system.

Do one thing.

First find the load currents at each node.

Starting from the last branch to 1st branch, find the effective branch current in each line by summing its sending end and receiving end node currents.

When you get branch current, you can find the voltage in forward direction.

Try to understand it..

Simply two steps to solve load flow.

@Raviteja16 • 24 May, 2014

In a distribution system, consider line P is in between nodes M (sending) and N (receiving).

for writing program in a general way, take the node N and find the line for which it is acting as receiving end node in the given line data using "find" command. Save that line number in a vector. later treat the sending node of the same line as receiving end node for next step. Repeat the same above.

So in second step, u'll get the line number (towards source side) which is connected to line L.

Repeat the same process until u get sending/receiving node = source node.

At final u'll get all the branches which are connected between source node and node at which DG is connected or a node from which u would like to measure the distance... After that u can find G and L easily.

If u know the total branches between source node and a node at which DG is connected, u can easily find the distance between them.Vanipd@Raviteja16 sir in ma base papr, they have mentioned about two parameters 'G' and 'L'.... how can we calculate that distances??

sir pls tell me how to apply GA on reconfiguration of radial nw to reduce losses

@Raviteja16 • 26 May, 2014

i dont have any idea about genetic algorithm.... 😔

My area is distributed generation integration in radial distribution system...shipra jhariyasir pls tell me how to apply GA on reconfiguration of radial nw to reduce losses

i dont have any idea about genetic algorithm.... 😔

@shipra jhariya • 26 May, 2014
no sir...thanks for valuable support.. 😀

@shipra jhariya • 26 May, 2014

m working over "reconfiguration of radial distribution network using GA " in MATLAB.

m not able make it relevant to each other

pls help me out

hello siryahya idriasyou can email me here mam : doomcoco671@gmail.com

hope that we can help each other.. 😀

sir @Raviteja16

can we incorporate DG into the load flow using FORWARD-BACKWARD METHOD??

can we incorporate DG into the load flow using FORWARD-BACKWARD METHOD??

@shipra jhariya • 28 May, 2014

mi thesis topic is reconfiguration of radial distribution network using GA

in matlab

pls help mee out how to make relevance between GA and reconfiguration. its urgent

maraitamilangenetic,differential, harmony search etc

hello sirAbhishek Rawal@shruti21 Why not share your Matlab code here itself ?

Many CEans will indirectly get help from your code too.

@Raviteja16 • 01 Jun, 2014

Yes we can...

there are some papers in ieeexplore related to your topic...

search for those....

@yahya idrias • 02 Jun, 2014
is there someone want to share the matlab code for this topic..?

i think it will very helpfull 😀

i think it will very helpfull 😀

@Vanipd • 27 Aug, 2014
hey frds............ have one dbt..... when i run the program coding (Harmony Search Algorithm) at different times........i got different solutions for each run....... y it is??

@maraitamilan • 27 Aug, 2014

it is evolutionary algorithm like learning from mistakes and improving... u ll get the same answer at intervals meaning every 5th time or every 6th timeVanipdhey frds............ have one dbt..... when i run the program coding (Harmony Search Algorithm) at different times........i got different solutions for each run....... y it is??

choose any other ga is done by manyshipra jhariyasir pls tell me how to apply GA on reconfiguration of radial nw to reduce losses

@Vanipd • 28 Aug, 2014
sir can u say abt evolutionary algorithm??

and which solution hav to b taken as optimal??

hello sir,

i am doing a project which i am not getting matlab code for this particular algorithm..i think you can help me with this problem..our project is "RECONFIGURATION OF DISTRIBUTION SYSTEM BY USING FLOWER POLLINATION ALGORITHM"....the main objective of this project to reduce the power losses in distribution network.can you please help me with the code that where i can get it or where i can learn to write the code for this particular topic.please help me sir.

@AndreaRodic • 24 Jun, 2015
Hi guys! I am new here, and I hope you colud help me with my problem. Well, I need to write code for power flow using back/forward sweep algorythm in Fortran programming language? But if not Fortran, maybe you can help me with Matlab or C++ and then I would convert it by myself?
