Hello everyone! I'm trying to find an optimal placement for a recloser using the optimization toolbox. The best place to set a recloser is defined by minimal SAIFI (system average interruption frequency index) value. I've created a little function where Nt - total number of customers, G - are some weights characterizing power lines, Xi - number of interrupted customers (if interruption happens in i-th line AND it has a recloser in it), Mi - row of 1 and 0 (that genetic algorithm should use as a gene I guess...) Here's the code of function:
function [S] = SAIFI_sum (M) Nt=270; G = [1.1 1.2 1.3 1.4 1.5 1.6]; X = [270 30 220 180 60 70]; for i=1:length(M) if M(i)== 1 N(i) = X(i); else N(i) = Nt; end end S = 0; for j=1:length(M) SAIFI(j) = N(j)*G(j); S = S + SAIFI(j); end S end As a result I have 51 same results: S = 297 and following message: "Optimization running. Objective function value: 297.0 Optimization terminated: average change in the fitness value less than options.FunctionTolerance". I couldn't understand how to solve this problem.
