hi everybody;

i want to find the value of (Pb_dis) from below equation and then make a loop to put (Pb_dis) value that i found from equation to (Pb1dis) to find (Pb_dis1) and to put the value of (Pb_dis1) to (Pb1dis) again to find (Pb_dis2) and so on . thank you very much i really appreciate it if you help me,

initial Pb1dis =3600 w

this is the equation:

Pb_dis= (Pb1dis*(1-sigma))-((Ppv/nu_i)-PL);

Thank you for your answer and spending your time ,

I share the entire equation with values. really appriciate it if you help me to solve this eq.

the original equation are:

Pb(t)= (Pb(t-1)*(1-sigma))-((Ppv(t)/nu_i)-PL(t)); %for li-ion battery discharging

Pb(t)= (Pb(t-1)*(1-sigma))+(Ppv(t)-(PL(t)/nu_i))*nu_b; %for li-ion battery Charging

Pb(t-1)= 3600 %SOC at the begining (Wh) >>watt hour

%Ppv(t) = 123.3 %Enegy of PV(photovoltaic ) (Wh)

%PL(t) = 60 %Load Demand (Wh)

sigma = 2 %Self_Discharge factor

nu_i = 0.9 %inverter effeciency

nu_b= 0.95 %battery effeciency

t=time

在 MATLAB Online 中打开

It would be something like this :

Pb1dis =inf; 
Pb_dis2=3600;
tol=0.0001;%tolerance
while abs(Pb_dis2-Pb_dis)>tol
    Pb_dis=Pb1dis2;
Pb_dis2= (Pb1dis*(1-sigma))-((Ppv/nu_i)-PL);
end
disp(Pb_dis2)
