If i run PV model in matlab I have face this problem. Pls guide me how to solve this error. if I increase the time 1e-7 simulation is running but very slow.

An error occurred while running the simulation and the simulation was terminated Caused by: Simulink cannot solve the algebraic loop containing 'pv970kw/PV Array 1/Diode Rsh/Product5' at time 5.0E-5 using the TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues. To rule out solver convergence as the cause of this error, either a) switch to LineSearch-based algorithm using set_param('pv970kw','AlgebraicLoopSolver','LineSearch') b) reducing the VariableStepDiscrete solver RelTol parameter so that the solver takes smaller time steps. If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.

Place a unit delay block in Simulink model between the blocks where algebraic loop occurs. I hope this will help you.
