I have been using the photovoltaic array under partial shading in matlab/simulink. However, when i try to get the characteristics without bypass diode the simulation do not execute.
Are you using the solar cell included in the Simscape toolbox or you are constructing your own model?
What I found to be helpful is to replace the equation-based model which is difficult to solve with a table lookup model which is constructed based on the data from the equation-based model.
I have been using both Simscape as well as own simulink but in both the types it is becoming difficult simulate the array characteristics without bypass diode. Can you please help how to replace equation-based model with lookup model@ Jacek Kapica
The table lookup model: the IV curve is a set of data - 1D table for a given insolation. Than if you want to change the insolation it becomes 2D table, than if you want to add temperature than it becomes a 3D table.First you run the equation-based model for various parameters to obtain the table data, which is than used in the lookup table block.
I hope this is helpful and understandable.
I think you should connect bypass diode to PV module to simulate it's p-v characteristics. The baypass diode in case of PSC protect the PV module from consumbtion some of power ( considered as load not generator )
The power voltage curve contains multiple local peaks and one global peak, and the number of peaks depends on the level of irradiance subjected to each module. The bypass diode doesn’t work in case of uniform irradiance, while under PSC it will be forward bias and used to protect the PV module from consumption of a part of the generated power by the shaded cell.
