Derivative of state '1' in block 'twodiodemppt1/powergui/EquivalentModel1/State-Space' at time 0.0084528571428571439 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the...
In the same manner, blocking diode (D2) is used to block the penetration of surges into the system. Simulation results give multiple peaks, i.e. various MPPs due to the presence of shading. Out of these MPP's, one is GMPP and remaining them are LMPP's for the whole array [21] ...
PVarray_Grid_PandO_avg.mdl is an average model of a 200-kW array connected to a 25-kV grid via two DC-DC boost converters and a single three-phase VSC. The MPPT controller based on the “Perturb and Observe” technique is implemented by means of a MATLAB Function block that generates ...
