Simulation Study on Photovoltaic Electrical Characteristics Based on Graphic User Interface

Photovoltaic array is one highly nonlinear power supply with related to many parameters,and its output characteristic is crucial for the relating research.Based on photovoltaic array project model and constant voltage control method against outer environment changes,a MATLAB Simulink simulation platform is established,and a characteristic analysis on the photovoltaic array output characteristics influence factors is produced accordingly.The simulation results show that this platform is of practicability and superiority and can be used as a practical photovoltaic array simulation analysis tool.
