Hey guys,

I've successfully modeled my solar aray in simulink and am getting correct output, but I'm having some trouble modeling an MPPT using the incremental conductance method.

if anyone has a model of it or can point me in the right direction I'd greatly appreciate it.

Thanks.

在 MATLAB Online 中打开

function dc = IC( V, I, Adc, dcinit)
%#codegen
%Algoritmo IncrementalConductance mi referencia es la dI/dV
% Isc=input ('Corriente de corto circuito=');
% Voc=input('Voltaje de circuito abierto=');
% Adc=3e-4; %variacion de ciclo de trabajo
persistent dcold Vold Iold
dataType = 'double';
if isempty(Vold)
    Vold=0;
    Iold=0;
    dcold=dcinit;
end
%calculo de errores
dV=V-Vold;
dI=I-Iold;
%
if dV==0
    if dI==0
        dc =dcold;
        return
    else
        if dI>0
            dc = dcold - Adc; %reduce V
        else
            dc = dcold + Adc; %incrementa V
        end
    end
else
    if I+(dI/dV)==0
        dc=dcold;
        return
    else
        if I+(dI/dV)>0
            dc = dcold + Adc; %incrementa V
        else
            dc = dcold - Adc; %reduce V
        end
    end
end
dcmax=0.95; %esto es para limitar los máximos y minimos del dc
dcmin=0.05;
if dc>=dcmax || dc<=dcmin
    dc=dcold;
end
dcold=dc;
Vold=V;
Iold=I;
