matlab跟电子信息的深切联系，在电子信息的应用。(matlab deep contact with the electronic information in the application of electronic information.)

The output characteristics of a photovoltaic (PV) array are highly non-linear. Therefore, an accurate andefficient PV model is required to study and analyze the operation of PV system in the changing environ-mental conditions. This paper proposes a precise PV simulator based on the seven-parameter electriccircuit model. The proposed simulator can generate the output characteristics of a PV system preciselyat different operating conditions. It has also enough flexibility to simulate different configurations ofPV panels with series/parallel connections. The robustness of the proposed simulator is demonstratedunder the partial shaded conditions. Additionally, the performance of the developed simulator is verifiedby interfacing it with the actual power electronic converter and maximum power point tracking (MPPT)controller. The proposed PV simulator will facilitate the design aspects of PV systems and help in behaviorassessment of newly developed controllers prior to practical implementation.
