With the promotion of the national "carbon peak and carbon neutrality" policy and related work, the two power grid companies in China put forward the control strategy of taking access to clean energy as the main body on the generation side, strengthening the consumption, energy storage, stability and safety of the power grid, and adopting the scheme of electric energy substitution on the user side. Under this development background, China's energy structure will be rapidly developed from fossil energy to clean and low-carbon energy. Renewable energy power generation will enter a large-scale "accelerated" development stage, and the proportion of non-fossil energy, such as wind power, photovoltaic, hydro-power, and nuclear power, will increase significantly. Accelerating the construction of new power systems will have a profound impact on the development of the power industry in the next 40 years. To achieve the "double carbon" goal, the energy field is the main battlefield, the power industry is the vanguard, the equipment manufacturing industry is the core support, and the power transmission and transformation equipment is the core priority. Facing the national "double carbon" goal and the action plan of major power users, Baiyun Power Group is supporting the construction and development of new power system by direct emission reduction, energy conservation and consumption reduction, supporting carbon reduction and green technology, and launch the following solutions: flexible DC transmission system solution, intelligent substation solution, prefabricated substation solution and smart distribution grid solution.
