opf_slvr.m

该程序是计算最优潮流的matlab工具箱。可以很好的求解目标函数不同的最优潮流问题。

function code = opf_slvr(alg)
%OPF_SLVR    Which OPF solver is used by alg.
%   code = opf_slvr(alg) returns a solver code given an algorithm code.
%   The codes are:
%       0 - 'constr' from Optimization Toolbox 1.x or 2.x
%       1 - 'LPconstr', dense LP-based solver
%       2 - 'LPconstr', sparse LP-based solver with relaxed constraints
%       3 - 'LPconstr', sparse LP-based solver with full set of constraints
%       4 - 'fmincon', from Optimization Toolbox 2.x and later
%       5 - 'minopf', MINOS-based solver
