The shunt current is a function of the PV current, forming an algebraic loop. Add a low-pass filter, with a frequency cut-off, e.g. 10kHz, in the feedback from the PV current to the shunt current.
If you got the loop error, verify this: for the photocurrent, you must correct the add block Isc + ki (in the video he sets it with a minus). Also, try observing the graphs with a scope if you have a problem visualizing them with the XY mode.

Sir I'm getting an errors algebraic loop in SHUNT CURRENT while running. Model is not converging. Can u PL help me out what should I do to get IV ND PV plots... Can u PL send me the model in my mail id
hello sir, i have some question 1.what should i do if i want to raise up the voltage value so i can raise up the power too? but without change the amount of Ns &Np and not change the value of Rs and Rp to? It's has been my problem since making PV modelling with MPPT and buckboost converter 2. Why do you choose ramp block as a voltage input? Thank you sir, i hope you can help me
Hello please How do you use different values of irradiance and temperature to obtain different curve? according to variation of the climate.kindly help
I am following exactly your steps but in the end I end up with algebraic loops inside PV Current and Shunt Current. I have tried a lot of things but it still didn't help. I wish i knew why even though i made the exact model like you, you don't have an algebraic loop and it runs smoothly😭
Can you please answer me a question. While in the model here you have used Vt i.e aKt/q in the diode reverse saturation current, i have noticed somewhere in a research paper that it is Vtn. i.e aKTn/q. The difference in the temperature value is my question. Tn is a constant i.e 298k while T is an input variable and depends on surrounding temperature.
Simulink cannot solve the algebraic loop containing 'durga/PV miodule /Shunt Current /Add' at time 0.08 using the TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues. To rule out solver convergence as the cause of this error, either a) switch to LineSearch-based algorithm using set_param('durga','AlgebraicLoopSolver','LineSearch') b) reducing the VariableStepDiscrete solver RelTol parameter so that the solver takes smaller time steps. If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.
I'm having some troubling using this model to simulate for variation in operating temperature. Everything else works perfectly at standard operating temperature. Any help?
Block diagram contains an Algebraic state in the algebraic loop, how can I fix this? I understand that this problem happens because of the I_PV feedback necessary to calculate Rsh current.

An error occurred while running the simulation and the simulation was terminated Caused by: Algebraic state in algebraic loop containing 'SinglePVmodule/PV module/PV current/Sum of Elements3' computed at time 0.0 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances) or tweak the initial guess of algebraic loop variable values. How can I solve this problem?
If u r getting a warning as "contains algebraic loop" Than add a memory block in PV current subsystem in between (I and feedback where u r providing) and also add memory block between output Current "I" & subsystem (shunt current) which goes input
please anyone help me please! why do we use Ramp for V ??? dont we want to get V as output ? why we use V as input and as a Ramp why is that i dont understand that it confuses me !
The final equation for "I" has both V and I as variables; It is required to get the I-V characteristics of the Photo system thus #we try to plot one variable against the other (plotting "I" has to be done for VARYing values of "V" ;this variation is what I believe the ramp function to introduce to the system) #hope I'm not sounding confusing?
can you please tell me why you add a ramp signal in ur model. and one more problem if i simulate with 4sec as run time iam getting 4V in display and if i change run time to 50 it is showing 50V in display. please reply.
We want to see the characteristics of power or current with changing of voltage, through this ramp signal we are getting increased voltage over time. So we use ramp signal. Your ramp slope will be 1 and simulation time also 1. You have to increase your voltage signal from zero to open circuit voltage So increase ramp slope in ramp signal parameter so that you get complete curve.
yes got the output by modifying the mistakes and trying for zero phase maintenance after power attains zero on x axis instead prolonging to negative raise. regards phd scholar
