Description

technical field [0001] The invention relates to the technical field of multi-energy complementation, in particular to a multi-energy complementary distributed energy system. Background technique [0002] Energy is an important material basis for the survival and development of human society. Fossil energy is still the main component of the world's energy structure, but with the consumption of fossil energy such as coal and oil, a series of environmental problems such as ozone layer destruction and climate warming have emerged. In order to alleviate this series of environmental and resource problems, new feasible solutions are constantly sought. However, the existing wind power generation is restricted by factors such as sunlight intensity, irradiation time, geographical location, and wind power. The power supply is not stable and cannot meet the needs of users. Therefore, it is very necessary to provide a multi-energy complementary energy supply system under the condition o...

In order to alleviate this series of environmental and resource problems, new feasible solutions are constantly sought. However, the existing wind power generation is restricted by factors such as sunlight intensity, irradiation time, geographical location, and wind power. The power supply is not stable and cannot meet the needs of users. Therefore, it is necessary to provide a multi-energy complementary energy supply system while ensuring the environment is not polluted.
