New energy refers to the renewable energy systematically developed and utilized on the basis of new technologies, such as solar energy, wind energy, biomass energy, geothermal energy, ocean energy, hydrogen energy, nuclear energy, etc. New energy power generation means using existing technologies to realize the process of power generation through the above-mentioned new energy sources. However, new energy power generation has the characteristics of intermittentity, randomness and volatility. In order to achieve safe and stable use of electricity, it must be equipped with enough and flexible adjustable power supply.
