在现代生活中，人们越来越离不开电能，偶尔的断电，都会让人们有突然的不适

In modern life, people are increasingly inseparable from electricity, and occasional power outages will make people suddenly uncomfortable. However, the large consumption of electric energy also consumes a large amount of energy used to produce electric energy. Since the establishment of the world's first thermal power plant, thermal power generation has always accounted for a large share of the power generation market, and it has also been accompanied by serious environmental pollution caused by thermal power generation. As humans demand a large amount of electric energy and need to protect the environment from pollution, the development of new energy sources has become a hot spot for electric energy development. Among them, wind energy and solar energy are the best choice among all green energy sources. Wind energy storage and solar energy storage are large and ubiquitous, and there is no pollution in the production process of wind power and photovoltaic power generation. <br>This paper mainly analyzes and simulates the control system of wind power grid-connected inverter and photovoltaic grid-connected inverter control system. For wind power generation, analyze the characteristics of the wind turbine and then analyze the simulation. Set the constant wind speed to 10m/s, the wind speed is the step wind speed, the result analysis and the analysis when the circuit fails. For photovoltaic power generation, the maximum power point (MPP) tracking of photovoltaic power generation is analyzed, and the solar array corresponds to the only equivalent internal impedance when it is operating in the MPP. The main examples are PI control, PR control, deadbeat control, etc.; then the simulation and analysis of the three-phase grid-connected inverter are established.

In modern life, people are more and more inseparable from electricity, the occasional power failure, will let people have a sudden inadaptation. But a lot of electricity is consumed, and a lot of energy is used to produce electricity. Since the establishment of the world's first thermal power plant, thermal power generation has been in the power generation market accounted for a large structural share, followed by thermal power generation brought about by serious environmental pollution. For human demand for a large amount of electricity, but also need to protect the environment from pollution, the development of new energy has become a hot spot for the development of electricity. Wind and solar energy are the best choices for all green energy sources. Wind energy storage, solar energy stock is large and ubiquitous, and wind power, photovoltaic power generation production process without pollution.<br>In this paper, the wind power grid-connected inverter control system, photovoltaic grid-connected inverter control system is analyzed and simulated. For wind power generation, the characteristics of the wind turbine are analyzed and then the simulation is analyzed. Set the wind speed constant to 10m/s, the result analysis when the wind speed is the step wind speed, and the analysis when the circuit fault. For photovoltaic power generation, the maximum power point (MPP) tracking of photovoltaic power generation is analyzed, and the solar array corresponds to the only equivalent internal impedance when running MPP. The main examples are PI control, PR control, non-difference shooting control, etc., and then the simulation and analysis of three-phase grid-connected inverters are established.

In modern life, people are more and more inseparable from electric energy. The occasional power failure will make people have a sudden discomfort. But the large consumption of electric energy, for the energy used to produce electric energy is also a large consumption.
