Thread Subject: PV Systems Modeling On Simulink

Good morning fellow MATLabers...

I am doing research on PV (Photovoltaic) System Degradation on panels... I was wondering if any of you know of any Simulink library that can be downloaded or that is available to Simulate the PV Systems.

Next I was wondering if anybody can guide me on how to create my own library or modify existing libraries to do exactly what I need.

Thanks

I think there is a block called solar cell in the newer version of MATLAB for use in SIMULINK environment.

Binod

I have version 2007a... i don't know if it is there... any ideas?

Hello

I have the latest version of Matlab 2009a with me. And yes, there is a module called solar cell in it. But from what I understand you can only use it as a independent cell, but not as a PV array or module. Secondly, when I tried connecting it to a inverter, it is not accepting the connections.

Concerning the modelling of a PV cell, i guess you have to build your own circuit version with a voltage source, diode, resistor and inductor.

Are you talking about the solar cell block in SimElectronics?
http://www.mathworks.com/access/helpdesk/help/toolbox/physmod/elec/ref/solarcell.html

It does represent a signle cell, but you could adjust the parameters to make
it represent an array of cells. Alternatively, you could model the array by
connecting as many solar cell blocks together as required.

By "inverter", are you referring to SimPowerSystems blocks? If so, you can't
connect a SimElectronics block directly to a SimPowerSystems block, as
they're not built on the same technology. You'd have to create your own
interface by measuring the voltage on the SimPowerSystems side and feeding
it to a voltage source on the Simscape/SimElectronics side, while at the
same time measuring the current on the Simscape/SimElectronics side and
feeding to a current source on the SimPowerSystems side.

HTH,

Arnaud

Hi, my friends. I am using the version of 2008a, and I don't have the solar cell model. Could you please tell me how can I update a new version?

If your license is under maintenance, you can just log in to your MathWorks
account and download the latest version:
http://www.mathworks.com/accesslogin/myAccount.do

Note that the solar cell is part of SimElectronics, which was new in R2008b
so in all likelihood, you will need to purchase it separately and add it to
your existing license. Contact sales for more information:

Hi,


I am doing a project to model a grid connected pv system using simulink.
I need to model an array with 18 parallel x 21 series module, where each module has 36 solar cells in series.
I use the solar cell block in SimElectronics. but it only works for a single solar cell.
I used to connect the solar cells together, it still works for a module.. but not for the array and the simulation time is super long.

Then i tried to adjust the parameters to make it represents as an array, but error occur on the solver block. It said.."Nonlinear solver: failed to converge, residual norm too large. Initial conditions solve failed to converge."..... maybe i need to adjust at the solver configuration block but i dont know what to adjust..
anyone has any idea?

thanks..

hello
I use the voltage control and the current control to connect my pv_array and converter, but the simulation time is too long and connot be converged at pv array. if i want to creat my pv array by lookup table, how to build?

hello friends

PV array can be built by one solar cells connected to another . the voltage of every cell can't be set higher than 0.6V, otherwise the simulation will be fail. the current can be set as you like, the version i use is 2009b

can u teach me how to create the input for the irradiance port for the solar cell?

Search in Simulink for the block named "PS Constant".

You should use the step source in the simulink. Link this to a S-PS converter. Use the initial time around 0.00001 seconds. It works for me.
See you
