Simulation research on the grid connected generation system of solar thermal power generation

ABSTRACT
Objective: To improve the conversion efficiency of photovoltaic power generation system, improve the power quality, and promote the optimization and development of solar thermal power generation. Methods: In this study, firstly, voltage feedback, power feedback, disturbance observation and conductance increment are used to track the maximum power of photovoltaic cells. After that, the problems and shortcomings of incremental conductance method are further optimized and improved. Then, the control of maximum power point tracking (MPPT) is expanded. Finally, in the Matlab software, the simulation model of power generation system is built. Results: The synchronization time of voltage and current is less than 0.1s. The current voltage and grid current voltage have the same frequency and phase. In the case of reactive power, the power factor of the system is close to 1. There is a certain relationship between the wave form of the active power and the illumination, and the illumination change will be found. The active power will also change with it, and the changing waveform is very similar to the light waveform, or even close to it. Conclusion: The simulation experiment shows that the optimized power generation system has great advantages and effectiveness, its dynamic response ability is very strong, and the output waveform of the power generation system can change with the sun light, which can effectively prevent the interference from the environment.
