Please see Sections 6.3 and 6.4 and Chapter 7 in the MATPOWER User’s Manual<http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-6.0.pdf>. If you need general non-linear costs, you will need to use the latest development version of MATPOWER on GitHub<https://github.com/MATPOWER/matpower/> You can find the corresponding version of the manual here<https://www.dropbox.com/s/3qkji1cuyi075uj/MATPOWER-manual.pdf?dl=0> describing how to use the non-linear user-defined costs and constraints. Regarding YALMIP, MATPOWER does not use it except when using SDP_PF, so you cannot use it to modify the problem normally solved by runopf().

I have a question about the objective function in OPF. Can the system add some user-defined function expecting the generators cost, Like power loss , voltage deviation ? And the matpower can be with some optimization tools like yalmip ? When I use yalmip , I define some variable but it can not be solve in matpower? Code like: clc;clear; x = sdpvar(14,1); assign(x,ones(14,1)); mpc = loadcase('case14'); mpc.bus(:,4) = mpc.bus(:,4) + value(x); mpopt = mpoption('verbose',0,'out.all',0); result = runpf(mpc,mpopt); f = sum(abs(get_losses(result))); F= [sum(x)<=50]; sdp_result = solvesdp(F,f); and the result show the yalmip is successfully sovled , but the result is not right. Hope you can help me. --------------------------------------------------------- Best regards, Wei Lin 林巍 Zhejiang University, Zheda Road 38#, Hangzhou, P.R.China, 310027 +86-13675865210
