int2ext.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 [bus, gen, branch, areas] = int2ext(i2e, bus, gen, branch, areas)
%INT2EXT   Converts internal to external bus numbering.
%   [bus, gen, branch, areas] = int2ext(i2e, bus, gen, branch, areas) converts
%   from the consecutive internal bus numbers back to the originals.
%   May be called as [bus, gen, branch] = int2ext(i2e, bus, gen, branch) if
%   area data is not available/needed.
