The invention relates to a multi-connected multi-group regional mutual-assisted power generation system, in particular to a power transmission and switching control technology capable of transmitting through an AC power grid, and the basic unit of the same interconnection can be superimposed and expanded according to the number of users. The multi-layer multi-group regional mutual-assisted power generation system integrates the natural energy power generation in the region and effectively reduces the environmental power system of the earth's resource consumption.

After the industrial revolution, fossil fuels were used extensively in various countries around the world. With the development of science and technology, the use of nuclear energy has become more and more popular. However, the use of these energy sources has caused great environmental impacts, including the leakage of nuclear energy and the greenhouse effect caused by a large amount of carbon dioxide emissions. The average temperature rises, and the acid rain caused by the combination of the exhaust gas and the rainwater causes environmental pollution, a large number of biological deaths, and great changes in the climate. The cause and effect planted in the past 100 years will eventually return to people.

At the same time, in recent years, humans have begun to think about replacing non-renewable energy with renewable energy, including hydropower, wind power, geothermal energy, ocean energy, waste conversion, solar energy and biomass energy.
