Anybody knows how to do a fuzzy distribution load flow using BIBC, BCBV and DLF matrices??

Lots of people certainly do. But what exactly is your question? It is not exactly a Matlab-related. Please show what you have done so far, and people here will be happy to help you.

well, it is matlab-related. I'm using the following program for the load flow

http://www.mathworks.com/matlabcentral/fileexchange/34200-radial-power-flow

and it gives me the BIBC,BCBV and DLF matrices all right. But these values are crisp values. I need them to be fuzzy.

As to what I've done so far, was to put the program in a loop so that the value of a variable changes after each run of the load-flow and then i get a rough estimate of how the power-flow varies. But this is impractical for reasons i've already given here:

Any suggestions would be greatly welcome.

You might not need to do random sampling. I would recommend you read up on fuzzy theory. If you have a simple membership function a few evaluations could suffice.

Also, how do you expect us to know that you are talking about a file exchange function? It is a good idea to make a question self contained, or at least to include all the necessary links.

Well, anything on fuzzy theory inexplicably turns up the "basic tipping problem" matlab example and this leads me nowhere. What would be interesting is to get only the fuzzification part of an FIS. Is this possible in matlab??

The membership function is a triangle and why do you say a simple membership function leads to a few evaluations?

The triangle is not the only possible membership function, although maybe the simplest.

I don't really understand what you are trying to do, but if your operations can be decomposed into sums, substractions, divisions and multiplications, then you can use the fuzzy logic toolbox.

Some effort would be required to rewrite the program using only fuzzy arithmetics.
