Abstract: This study explored the dynamic characteristics and monitoring design of the photovoltaic energy conversion system, which is a system model of an independent power supply. This study first established the non-linear differential equation of the system model, linearized the model, and analyzed the eigenvalues and dynamic response of the system using the MATLAB program. The dynamic characteristics of the photovoltaic energy conversion system were obtained from systematic analysis. In addition, this study used the main controller in industrial automation, programmable logic controller (PLC), to monitor the overall system and the electric energy of solar cells. It employed the man-machine interface application program to construct a PLC monitoring system of network graphic monitoring. The personal computer (PC) was connected to the PLC through the RS232 port, and the changes in voltage and current were monitored on the PC display. Finally, the accuracy of the model was!
verified by the operating points, eigenvalues, and dynamic response.
Keywords: Dynamic Characteristics, Programmable Logic Controller, Monitoring System, Photovoltaic, Solar Cell, Eigenvalue.
