PV module simulation

Which toolbox i will be used in PV module simulation?

[Andrew Alkiviades]

Hi Nuno,

Are you using the single diode equivalent circuit?

Do you have the series and shunt resistances for the module you are looking at?

[Muhammad Talha]

Hello guys i need help regarding my final year project i mathematically model a PV cell where output is Current and voltage so i can get easily output waveform accurately but i dont know how can i convert this module to PV array model like in simulink Built in block where we get + or - sign and how i can i attached boost converter with my model

Answer 1

[Arnaud Miege]

It depends on what you want to. If you want to model the photovoltaic cell, then you'll probably need Simscape and SimElectronics, which has a Solar Cell block. If you are interested in modelling the connection to the grid and the DC/AC conversion, then you'll probably need SimPowerSystems. have a look at the webinar Model-Based Design for Solar Power Systems for more information.

HTH,

Arnaud

[Nuno]

Thanks! I want to model the photovoltaic cell...

[Hossein]

Hi Arnaud,

I have use the matlab model of solar cell block in simscape,entitled:('elec_solar'),but when i change Isc and Voc appears some error (Isc=8.36 and Voc=33.2)

maybe i have to change the voltage pulse?

and is there any parameter in solar cell block to define number or series or parallel cell?as it was exist this parameter in pervious version?

Regars,

[Hossein]

Hi Arnaud,

as I found we can connect simscape and simpower together ,So there is another way to simulation,which is mix both of them...

for example using Solar Cell block from simscape and connect to DC/DC converter from simpower ...

Is it right????

[Mohan]

I need some help in grid connection of inverter. i have attached a model, in which the current from inverter + grid = load. they r not in phase bt are getting added up...,,, if there s a mistake n PLL pls help me crct it

hi,am also working on MPPT.. for the PV module u can go for either coding or modelling using blocks...if u r intrested in modelling using blocks then u can easily do it with the help of commonly used blocks,sinks,sources,math operations in simulink otherwise u can go for simpower system ,there u can directly take diode,sources,MOSFET etc..

[Hossein]

hi Ambika,

Do you have any experience about connecting simpower and simscape?

I mean connecting the solar cell block in simscape to DC-DC converter in simpower ???

How can I find "Model-Based Design for Solar Power Systems" Webinar???????????????

How can I find out the values in temperature tab of the solar cell,(temperature exponents of saturation current(Is),series and parallel resistances(Rs & Rp) and what is the first order temperature coefficient?

[shrik kader]

What are these two links? when I click on them it turn me back to this comment.

Thank you very much Lucas,I have looked to this webinar so much,you help me with webinar so much...

Hi Folks,

I am working on project that is to develop a small-scale solar system (solar harvester) to charge rechargerable batteries of a Wireless Sensor Devices/Nodes). I need to design and simulate a system that work with MPPT but I have no idea on how to implement MPPT to drive the gate pin of MOSFET as seen on the video link above.

I look up to your propositon.

Answer 6

[Hossein]

Hi Menara, The main duty and output of MPPT is generate duty cycle for DC/DC converter or DC/AC inverter ,so you can refer the duty cycle to MOSFET to adjust the voltage of Photovoltaic panel to find the knee(maximum power point) of I-V curve,becuse in this point you have the maximum area under I-V curve and conclude the maximum power...

Answer 7

[Alfred Baams]

what is appropriate device or components to be use to stabilises the pv array model before connection to dc boost converter?

[Tony Castillo]

I think you can gain stabilization in that point with a simple Capacitor. Did you do it?

Answer 8

[SHOUTRIK DAS]

Hi, I"m designing a MPPT system for a PV module.

I have designed the PV module and used the current output from the pv module subsystem as the control signal for a controlled current source.

Before connecting the controlled current source the output from the PV module is a smooth curve.

After connecting the Current source it looks like this.

How to solve this issue??

[SINDHUJA D]

Hi,

I am designing a Incremental Conductance MPPT based solar panel both series and parallel connection. I faced a problem while connecting a solar 4 strings are in parallel connection. In parallel Connection current value not added .

Is there any solution.
