Incremental Conductance in simulink
显示 更早的评论
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.

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

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;
