以上所传的内容为电力系统比较全面的分析程序,才用的是matlab编写m的文件

function [PW_LINEAR, POLYNOMIAL, MODEL, STARTUP, SHUTDOWN, N, COST] = idx_cost
%IDX_COST   Defines variables for column indices to gencost.
%   [PW_LINEAR, POLYNOMIAL, MODEL, STARTUP, SHUTDOWN, N, COST] = idx_cost

%% define cost models
PW_LINEAR   = 1;
POLYNOMIAL  = 2;

%% define the indices
MODEL       = 1;    %% cost model, 1 - piecewise linear, 2 - polynomial 
STARTUP     = 2;    %% startup cost in US dollars
SHUTDOWN    = 3;    %% shutdown cost in US dollars
N           = 4;    %% number breakpoints in piecewise linear cost function,
                    %% or number of coefficients in polynomial cost function
COST        = 5;    %% beginning of cost parameters,
                    %% piecewise linear data as:
                    %%      x0, y0, x1, y1, x2, y2, ...
                    %% and polynomial data as:
                    %%      c2, c1, c0
                    %% where the polynomial is c2*P^2 + c1*P + c0
                    %% note: polynomials can be of any degree, highest
                    %% order coefficient always goes first
