MATLAB: How to make the simulation of photovoltaic with constant power load work..

Question

i'm make a model of photovoltaic with constant power load but when i try to simulate it, it shows that one of the blocks in my simulation which is the divide block is in error.. the message states that "Algebraic state in algebraic loop containing 'RL/Divide' computed at time 0.0 is Inf or NaN. There may be a singularity in the solution" .i try to reduce the step size and change the solver but it still the same..

Answer 1

I think use limiter or saturation at dividing part and make lover limit as less value, like 0.0001, and upper limit as inf. then may be your problem will solve. other wise, I uploaded a PV model, you can download this.
