Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to a multi-energy storage device coordination system and method based on a wind-solar-electric-heat-gas conversion module. Background technique [0002] Energy has always played an important role in human social and economic development. At present, non-renewable fossil energy such as oil, coal and natural gas is still the main energy source for the survival of human society. As the global economy and population continue to grow rapidly, the world's demand for energy is also increasing. However, due to the non-renewability of these fossil energy sources, with the over-exploitation of human beings, the non-renewable fossil energy sources are about to be exhausted. This makes the energy crisis increasingly prominent. At the same time, the extensive use of fossil fuels has also had a serious negative impact on the earth's environment. For example, the substances produce...

Problems solved by technology

Wind power, solar energy, etc. are affected by natural conditions, and their output power is intermittent and random. The large-scale grid connection of this type of renewable energy has brought huge challenges to the stable operation of the power grid.

In many cases, it is difficult to match the demand on the load side with the energy supply of distributed clean and renewable energy, resulting in large-scale abandoned wind, abandoned electricity and other energy waste phenomena
