Re: Compare case

Sat, 15 Jul 2017 08:42:36 -0700 

compare_case() cannot be used on two different networks. It compares the 
runpf() (or runopf()) outputs for two different scenarios on the “same” network.

For example,
mpc1 = runpf(‘case9’);        % run power flow on 9-bus network
mpc2 = loadcase(‘case9’);    % load 9-bus network
mpc2.branch(8,11) = 0;  % Turn off branch 8-9
mpc2 = runpf(mpc2);   % run power flow on the modified 9-bus network
compare_case(mpc1,mpc2);   TCL MERGE ERROR ( 07/15/2017 11:42:22 ): "invalid

 Subject: Compare case
 
 hello to everyone,
 I am studying the compare_case function and while I am comparing the two case 
i.e. case5 and case9 by using the following command-
 mpc1=loadcase(case5);
 mpc2=loadcase(case9);
 compare_case(mpc1,mpc2)
 It is giving the following error-
 Error using  -
 Matrix dimensions must agree.
 
 Error in compare_case (line 127)
 [temp, i] = max(abs(bus1(:, 1:Nb) - bus2(:, 1:Nb)));
 
 How this function used??
