This model is just I was looking for my bachelor's final project to inspire.
I do admire your modular design and comprehensive plots. Just to share, I'm trying to simulate MPPT charge controller for a small wind turbine, I selected a modified Hill-Climbing-search algorithm, which in this specific application might be faster in convergence. For sure I will not use the model itself in my work, but as I learned a lot from every single block, I will refer to your great design. After all, I wish I could generate the controller code for actual implementation and further verification tests.
Also, I'd like to add a convergence speed calculator and maybe a programmable step size feature. If I was successful I'll post it for your review.
Great model. However i want to simulate for a 10 hour sunlight which is a 10*3600 seconds of simulation time and it gets so slow. Will decreasing the delta value or make the powergui continue help?
Please, I need this model in R2015a.. Thank You
