Abstract
In the face of the increasingly serious global energy crisis, the development and
utilization of renewable energy has attracted great attention.Among them, radiation to
the earth's solar energy resources is very rich, green and clean solar energy will not
harm our living environment, so it has been widely used by people.Photovoltaic power
generation as a renewable energy is widely used, technology innovation.In order to
improve the photoelectric conversion efficiency of photovoltaic power generation
system, the system needs to track the maximum power point in real time.
Due to the improvement of people's living standard, the continuous progress of
science and technology, and the continuous improvement of control, the consumption
of non-renewable energy is serious or even exhausted, thus promoting the renewable
energy to become the leading industry.Photovoltaic power generation has become a
beautiful landscape at the present stage. Due to its advantages of mature development
technology, relatively small cost and almost no pollution, it has a high prospect in the
new energy power generation industry and has become the focus of attention of all
countries in the world.At the same time, due to the variability, randomness and
uncontrollability of light intensity, the stability of photovoltaic power generation
system is greatly affected.The photovoltaic power generation industry continues to
innovate, generating more and more electricity.Therefore, the new generation of us
should seriously study the impact of photovoltaic power generation.
Firstly, a comprehensive theoretical analysis of grid-connected operation of
photovoltaic power generation system is carried out, and the research object is idealized.
Through in-depth thinking of the parallel operation of two ideal power supplies, the
influencing factors of power quality in grid-connected mode are revealed, which
provides a direction for the study of control strategy.
Then, based on the user's actual demand for photovoltaic power generation system,
the function and working mode of single-phase photovoltaic power supply system is
designed. Through theoretical analysis and simulation experiments, the proper main
circuit form is determined, and the design and parameter selection of each module in
