The future will usher in a green and low-carbon digital energy era. The main role of traditional fossil energy power generation will gradually be shaken, and renewable energy such as wind power, photovoltaic and hydropower will become the main new energy sources. With the application of energy storage technology in the power generation side, power grid side and power consumption side, the leapfrog development of renewable energy will be promoted, and a high proportion of renewable energy will be friendly connected to the power system. The process of electrification on the consumer side will be accelerated, and the pace of replacing oil, gas and coal with electricity at energy consumption terminals such as transportation and heating will be accelerated. More and more advanced "plug-ins" will be connected to the energy system. Based on energy storage technology, with the help of power generation side prediction Demand side response and grid side intelligent dispatching can realize a safe, efficient and stable intelligent energy management system integrating source network storage and load and a new power system. The information flow and energy flow can be fully integrated to form an energy cloud "operating system", which connects energy production and energy consumption, promotes the interconnection of energy participants such as source, network, load, storage and people, and truly realizes Internet style two-way interaction.
