Simulation of Tracking Control Modeling of the Photovoltaic System with Maximum Power

Abstract:

This paper mainly studies the off grid wind solar hybrid power supply system based on the DC bus, a practical mathematical model, implemented in MATLAB software on the system modeling and simulation. Through controlling the light intensity, temperature and other environmental parameters, operating characteristics of the system, analysis of system output voltage (current), dynamic and steady-state output power parameters. On the basis of the maximum power point tracking (MPPT) problem, and the maximum power point of PV power generation system tracking (MPPT) in-depth simulation experiments, using variable step perturbation and observation method, and the corresponding simulation model is established in MATLAB, changes in the environment variable parameters of the system can make timely adjustment re operation, in the vicinity of the maximum power point, and the work efficiency and the operating characteristics of the system through the analysis of the problem.
